A/N: I posted this fic in Ao3 as well, but with a slightly different title because FF has a title limit :) The original title is "What To Do When Your Terror Professor Accidentally Left His Camera Open After A Discussion".

Armin Arlert typing…

Armin: Eren, please tell Mr. Ackerman now. Please.

Connie: No

Connie: Don't you guys dare leave the meeting.

Connie: YET

Connie: Just wait

Connie: WHAT IF HE DOES SOMETHING FUNNY

Eren tentatively types then deletes the words on his screen. For the last three minutes, he ponders on what to say to his classmates—or his chemistry professor—and settles for a simple, "Why me?!", because really, there are almost 20 of them in the class and he's not even the class' president for heaven's sake but his classmates push him to go chat their terror professor who is currently reading some documents and is totally unaware of his camera that's been left open five minutes ago after their class ends.

Jean: Of course, it should be you, Jaeger.

Jean Kirstein typing…

Jean: Since you always love to suck up to Mr. Ackerman.

Jean: Bootlicking asshole.

Eren: Fuck you, horse face. Why don't you try and tell him instead since you are a good pony?

Marco: Language, guys. Language.

Armin: Guys, please don't fight here on the class' group chat again!

Armin: Mikasa, please do something.

Hearing a soft feminine voice from their professor's other side of the screen, the banters in their group chat die down. Eren—and presumably the rest of his classmates who refuse to leave the meeting—watches as a familiar short woman enters their professor's home office. Mr. Ackerman looks up from his stack of papers as he—wait, did Mr. Ackerman just smile?—acknowledges this new figure.

Connie: HOLY SHIT

Marco: Connie, language.

Connie: HOLY SHIP

Connie: Is that, Ms. Ral?

Sasha: They're a thing?

Historia: I think so?

Sasha: Since when?

Jean: Hey, Eren Bootlicker. You know about this?

Eren: Do I look like their couple advisor or something, horsie?

As much as he hates Jean for calling him the silly name, Eren is surprised like everyone else.

In the university, it is common for students to have Ms. Ral as their favorite professor. She always has this smile on her face, sunny and so cheerful. She also teaches well and kind and patient to students who are having difficulties learning a specific topic (he's one of those students).

At the same time, it is also common for students to be afraid of Mr. Ackerman. An intimidating, terror professor who makes students cower in fear just by his sharp looks. But in reality, he's a great educator and even if he doesn't look like it, he's very considerate too.

But still, he just has this image of being terror and frightening. It surprises them so much to see Ms. Ral—the literal sunshine, and Mr. Ackerman—the embodiment of darkness and the most accurate representation of a person who's mad with the world—living together.

But it surprises them more when Mr. Ackerman pushes his documents to the edge of the table and casually opens his arms as the female professor approaches him. Ms. Ral runs to his arms, a visible blush is evident on her bare and mushy face fresh from sleep. She settles in their professor's lap and snuggles in his chest, burying her face on the crook of his neck.

"Good morning," she says groggily.

"Hmm." Mr. Ackerman hums and softly rubs Ms. Ral's robe-covered back.

For a couple of minutes, Eren watches as the two snuggles together until a message notification pops up again on his computer.

Historia: Oh my god

Historia: They're cute

Marco: I didn't know Mr. Ackerman has a soft side…

Armin: You guys do understand that we are invading their privacy, right?

Mikasa: No.

Mikasa: We need to watch.

Mikasa: I think shortie's threatening Ms. Ral.

Mikasa: Armin, record this so we have evidence.

Armin: Mikasa? He's literally your cousin. Don't you suppose to know him?

Mikasa: Exactly. I know how awkward that shortie is. Ms. Ral won't date him unless he did underhanded tricks.

Connie: GUYS

Connie: WHAT IF THEY DO IT

Connie: RIGHT NOW

Jean: DUDE

Sasha: CONNIE WTF

"Want to eat breakfast?"

Ms. Ral has her arms around Mr. Ackerman's neck as the male professor caresses her orange hair.

"Hmm. Later. I still want to sleep." Ms. Ral places a soft kiss on his neck.

"It's already past 8. You sure you're not hungry yet?"

"Not yet."

Their exchange of words is peaceful and warm. From the looks of it, the two may have been together for quite a while now.

Armin: I really think we need to leave the meeting now, guys. We're going to be late for Mr. Smith's class.

Reading Armin's chat in his inbox, not one of them replies as they watch Mr. Ackerman fix Ms. Ral's sleeping robe. Their professor watches the sleeping figure of Ms. Ral lovingly and plants a soft kiss on her forehead before dozing off as well.

They hear their soft breathing as well as the sound of the aircon from the other side. One by one, Eren and his classmates leave the meeting. The image of their two professors sleeping peacefully around each other engraves in their minds until the day ends.

Levi awoke with Petra's robe drape on his body, his girlfriend nowhere to be found as his eyes slowly adjust to the light on his home office. With his open laptop on the table, Levi tries to distinguish what time it is only to find out that it is drain of its battery. He takes his phone and sees a bunch of missed calls from Mikasa and some text messages from Erwin that says, "You took your time with Block 104. They didn't attend my class. We have to talk about this over Zoom, Levi."
