Author's note: I'm gonna change the rating because this is based on chapters 42 and….. 44 of the manga

Denji is in his apartment at a Friday night chilling and he received a Line message from Reze

(Reze) Bombgirl: Can we go to school later I wanna do something special at night meet me at 20:00

(Denji) Chainsawman: This is unexpected how come?

Bombgirl: Just this once okay

Chainsawman: Alright meet yah at 8

Then Denji and Reze meet together at the school gate at late hours and they went inside the school premises

"It's really spooky in the dark" Reze said

"This isn't my first time going to school at night" Denji said

"How come?" Reze asked.

Because me and friends of mine we went ghost hunting" Denji said.

"When did this happened" Reze asked

"Last month, I got used to the darkness" Denji said.

"Oh I see" Reze said.

The Reze held Denji's hand as they go to the outdoor swimming pool

Tested the wanted and she said "so cold" in Russian

"I'm sorry I don't know how to swim" Denji said.

Then Reze undressed herself

"Why are you stripping?" Denji asked in a confused tone

"You want to learn how to swim right" Reze said.

As Reze starts stripping naked the only one Denji sees a naked girl is Power like in their elementary years. But Denji is now a teenager and he's stunned that he's seeing a naked girl. He can see her breasts and vagina but there's nothing sexual going on just two kids in love. Then he's started stripping naked and said "fuck me."

Then Reze dips herself first in the pool and said "Denji, look the water is fine."

Then Denji jumps and Reze can see his penis that both of them just took a swim nakedly. The water splashes all over her and and Denji ascend from the water.

"I'll teach you" Reze raised her arms to Denji as Denji paddles on the pool with Reze

"Nice job, Denji" Reze praised him

Denji pants and he said "couldn't say better myself" as he splashes water to Reze and they played each other in the pool

Sometime later Denji and Reze are on the poolside but they're still naked. Reze's sitting on the poolside and Denji's lying on her lap

"So what do you think" Reze said

"Ecstatic" Denji replied

Both of them laugh and Denji's just wondering "Reze, can I ask you something?"

"Yes, Denji-kun" Reze said.

Denji gets up and said "Ever since I met you you're the one that light up my life, and I don't wanna lose, I wanna be with you forever. Reze-chan. I like you, will you be my girlfriend?"

Reze got teary eyed from Denji's proposal and she hugged him "Yes, yes, a million times yes! I do feel the same way towards you. I like you Denji, and I want you to be my boyfriend."

Then Denji hugs back and after several seconds Reze pulled away from the hug and started kissing him three seconds later she accidentally bit Denji's tongue as he pulls away.

"I'm sorry, did I bit your tongue?" Reze said anxiously

"It's alright, let's do it again" Denji said

Reze replied with a hmmm and nodded and they kissed together again several seconds later they make love.
