Tubby's Notes:

Name: Sucrose

Occupation: Knights of Favonius Alchemist specializing in Bio-Alchemy

Profile: Kuudure. Extremely shy. Obsessed with her research. Sucrose is timid, easily intimidated by important figures. Her ideal day would be conducting experiments every single hour.

She's compassionate, humble, and especially supportive of other peoples' academic pursuits. Sucrose helped Klee create her Jumpty Dumpty bombs. On one hand, that's nice. On the other hand, she enables that little terrorist to wreak havoc on Teyvat.

Overall, she's extremely wholesome. Yes, I don't think any debauchery will ever come from her.

Sucrose had performed countless experiments, but this had to be her craziest one yet. In preparation for her date, she'd experimented with some different styles. Standing before the mirror, she took herself in. Her alchemist attire had been traded for something a little more risqué. Sucrose opened her notepad and scrawled some notes.

Hypothesis 1: Wearing contacts instead of glasses will not give me a new kind of allure.

Results: Pending. Discovered that contacts are itchy, but don't fog up.

Hypothesis 2: Applying makeup to cheeks along with glossy lipstick will not make me beautiful and could never feel natural.

Results: Nothing about this feels natural. Beauty is subjective, but adding all these extra layers of makeup makes me feel like a harlequin.

Hypothesis 3: Exchanging my usual attire for a daring style emphasizing my femininity will not make me feel uncomfortable and will not make me more attractive.

Results: I am incredibly uncomfortable. My figure is unsuitable for this dress. Scrawny and sickly looking, my body lacks appeal. In short, I feel ridiculous, not attractive.

Oh, what was she doing? She couldn't pull this off. A sleeveless halter dress that flaunted her shoulders would've looked gorgeous on Lisa. On her? Sucrose looked like a ragdoll playing dress up.

This wouldn't work. She scrawled some notes, hypothesizing her failure if she went through with this. She further hypothesized she would be better off putting on something casual. Perhaps baggy clothes would hide her diminutive, unappealing features.

Knock, knock, knock.

Sucrose yelped in panic.

"Sucrose?" Aether called from the other side. "I heard you in there. May I come in?"

Already? She was sure she had more time before he showed up. What now? Maybe she could still change if she got to the closet and—

"Sucrose? Are you okay?"

His voice rose in urgency. Her voice failed her.

"I'm coming in!"

Her door flew open, and he burst into her room. Sucrose turned around and saw him standing in her doorway. Aether's eyes widened. Sucrose screamed, throwing her face into her hands.

"Don't look at me!"

"Hey, hey, it's okay," he said gently. "I'm sorry I barged in here. I was worried."

Aether soaked in her weird body. She squirmed. Her eyes grew watery. Tears threatened to smudge away her makeup. Her legs quivered violently as she tried to breathe. She got so embarrassed she thought she might die.

"I'm sorry, I'm sorry, I'm sorry," she cried.

His gentle smile fell on her.

"Sucrose," he said. "Did you put this on for me?"

Her eyes fell to the floor. She surrendered a nod. Aether's smile broadened.

"Sweetheart. This is…I don't know what to say. You went out of your comfort zone just for me. Do you know how special this makes me feel?"

Sucrose shifted between her feet.

She murmured, "You don't think I look …weird?"

He crossed the room, gently taking her hands into his. Aether guided her fingertip below his jaw. She didn't understand why. Until she felt his heartbeat. It was racing high above the natural rate.

"You feel that? You caused this. You."

They stood there, totally silent. Sucrose allowed herself to smile. Perhaps, she could do this after all.

"I um," she stammered, "I had a hypothesis you would think this makes me look weird, but… I guess you disproved it."

"Well, are there any other hypotheses you'd like to test?"

She bit her lip. As a matter of fact, there were.

Excerpts from Sucrose's Research Notes:

Hypothesis 41: If Aether sees me in lingerie, he will not be aroused.

Results: Hypothesis rejected. He went hard in an instant. Impressive reaction time.

Hypothesis 43: Aether will not purport enjoyment from our shared practice of philematology.

Results: Hypothesis rejected. Aether and I made out for a long time.

Hypothesis 45: Aether will not enjoy my attempts at stimulating his testicles via hand massage.

Results: Hypothesis rejected. He couldn't stop staying, "Sucrose, you're so good at this."

Hypothesis 49 Aether will not enjoy my attempts at fellatio.

Results: Hypothesis COMPLETELY rejected. He loved it.

Hypothesis 50: If I ask Aether for sex, he will not agree.

Results: Hypothesis couldn't be more COMPLETELY rejected. We went for hours.

Hypothesis 51: Copulation attempts will not go well.

Results: Hypothesis COMPLETELY rejected. It was for lack of better words freaking incredible!

Hypothesis 53: Aether would not agree to letting me "peg" him. I would not be much too shy to actually ask much less to actually penetrate him.

Results: Hypothesis rejected. He said yes, so long as I utilized adequate amounts of lubricant. Honestly, I enjoyed the experience. Taking control is rather stimulating.

Hypothesis 56: Aether would not consent to taking a drug that would temporarily change his gender. Moreover, he would not consent to allowing me to dominate his female genitalia.

Results: Hypothesis rejected. He did. I also enjoyed this experience as well. Though, I think we both prefer normal intercourse. This gender swap thing is a little too confusing for us both. As a side note, Aether makes for a surprisingly cute girl. I must make sure this information is kept secret from Lisa.

Hypothesis 1,234: Aether will not agree to let me fall asleep in his arms. He will not stroke my hair and whisper to me as I fall asleep to the sounds of his heartbeat.

Results: Hypothesis rejected.

Conclusion:

Aether is an agreeable research partner who adores me. He trusts me enough to do anything I ask of him, no matter how bizarre or inane. Although we established safe words, they never came into play.

He let me run several experiments. I believed his intent was boosting my self-esteem, making me feel comfortable, and just having fun with me.

Falling asleep in his arms was wonderful. For a moment, I truly believed myself beautiful like Lisa or Rosaria. Aether showed special fondness for groping my posterior, running his fingers through my hair, and whispering sweet nothings. Even my breasts, which are small in comparison to Hu Tao's, greatly excited him. Aether truly finds me attractive, although I cannot say why. This may require further research.

Moreover, this experiment led to some revealing insights. Aether lacks a refractory period. He can orgasm multiple times and never run dry. Even more remarkable though, it seems his seed has incredible effects. Since our date, I have not had my typical menstrual cycles these last two months. I took several pregnancy tests and always came up negative. The menstrual cycle finally resumed on the next month.

Theory: Aether's seed might be capable of temporarily suppressing menstrual cycles.

I must conduct further research to verify this observation.

Tubby's Notes Adjustments:

I was wrong. Sucrose is at heart a scientist. Scientists constantly push the boundaries of the natural world and what's possible. Normally, she is extremely shy. When it comes to Aether though, she's willing to experiment. She's not wholesome. She's a freaking mad scientist.

Never, under any circumstances, let Yae Miko discover her research notes.
