Futaba decides to visit Takuma in the hospital after his accident and meets Osamu’s piano teacher there. Her name is Honami Ruka and she’s known Osamu since he was three years old. Futaba smells the same perfume from Osamu on her. After picking up a book she left, she leaves the hospital room and Futaba finds her in the waiting room with Osamu getting all familiar with each other. Matsunaga appears telling her they could definitely be lovers but Futaba is in disbelief that she’d have an affair with Osamu whos significantly younger and since she’s married. Osamu notices them and indirectly tells Matsunaga to gtfo already. Futaba tells Ruka to be careful when she’s getting all touchy with with Osamu to not cause a misunderstanding.
So Osamu continues to be tired all the time and Futaba starts suspecting there’s something up between him and Ruka. Futaba even finds him asleep in the meeting room and when his phone goes off, its Ruka who’s calling him. So when Futaba brings up wanting to talk to him he says he made a promise to meet someone so he can’t. But Futaba pushes further and asks who he’s meeting. She gets him to confirm it’s indeed Ruka and drives him to her place. When she does, she stops him before he can leave and tells him not to go. Suddenly, Ruka appears and urges Osamu to come inside (omg thats what she said).
Futaba tells her to back the fuck off though and that she won’t allow them to associate like this any more. She decides to back off for now but tells Osamu to contact her. Osamu then confirms with Futaba that he indeed is seeing Ruka and they’re more than just student and teacher and he had been comforting her (with sex) because she’s lonely af with her husband traveling and being a away all the time. Futaba tells him she’s worried about him though and knows this sort of affair is not a good thing for him and he’ll only end up heartbroken. She hugs him to confort him and manages to convince him not to see him anymore.
So the next day, Takuma is teasing Osamu about him being close to Futaba but Osamu doesn’t deny it. Right in front of everyone he confesses he’s in love with Futaba and kisses her right then and there saying there’s no turning back now!! A few days later Osamu talks with Futaba at the party (and she apologizes for accidently wacking him in the face) on how he feels. He tells her again that he loves her and decided that when she said she wanted to fill the hole in his heart, he realized he loves her (ok???). He also completely stopped seeing his teacher with benefits. Futaba didn’t reject him but can’t answer his feelings right now and tells him to wait until his live his over to try and think her feelings over. Osamu tells her he understands and will respect her decision.
She then takes out a box cutter and threatens Futaba with it while Osamu protects her. ((Albeit, he was pretty fucking chill in this scene?? What in the fuck?? He even says even more shit to her that would make any batshit women go crazier than they already are by basically saying Futaba is all I want so fuck you. He didn’t even try to calm the girl so yeah she ends up giving up but for some reason they drop the fact this bitch is crazy?? what the fuck was that weird bullshit??)) anyway admist the fuckery Futaba realizes she’s in love with Osamu so finally confesses her feelings so they’re offically dating with no more secrets.
So a month and a half later Futaba meets with Osamu after hearing rumors about a scandal. He blackmails to reveal a picture of Osamu and her kissing in her car. But before Futaba can answer, Osamu appears and kisses Futaba in front of him telling him he can go ahead and reveal it if he wants. This makes Osamu not want to anymore so he leaves it be (as per every route??). So they finally go on an actual date together and when Osamu brings her to his place he finally gets to bang Futaba like he did sensei 👍. Later Osamu writes a song just for Futaba and performs it for her alone.
