==========================
There's two major routes that branches into paths.
The Childhood Friend, Haruna, confesses to MC, Seiichi, that her senpai, Yuuma, stole a kiss and confessed to her, the MC gets mad but is happy that his now girlfriend told him that instead of hiding it, he then asks if she will be strong enough to now refuse Yuuma if he ever tries something like this again.
- First Major Route: Haruna says yes, she will refuse Yuuma, that she won't betray the Seiichi's trust after being the one who said that would heal him. However the MC doesn't really take that answer to heart, he feels something will happen out his fear and prejudice of women.
With lingering suspicion Seiichi feels he has get over his issues against being close to women fast, so he is the one to take his gf's virginity; still his girl is not very strong willed and Yuuma is really forceful so they start having an affair, Haruna feels guilty the whole time but can't bring herself to refuse it.
In this route the Seiichi finds out he has been getting cheated on by catching his girlfriend and the senpai having sex in the tennis club storage room, he loses his mind, Haruna comes out and pleads for forgiveness, Seiichi then asks what he mean to her after all, she desperately cries he is the first man in her life, then he coldly replies with asking "then Yuuma is your second man?" with this assertion Haruna loses her footing, just now realizing her words mean Yuuma means something to her after all, the MC then says he doesn't want to be the first man in her life, he wants to be the ONLY man in her life, he leaves.
This makes the klutz girl realize what she has been doing and gather the courage to angrily tell Yuuma to back off, Yuuma isn't a generic NTR dude, he actually is a nice guy (who pulls moves on someone else's girl but still) who loved the girl and with her resolve he does back off.
The next day the girl begs for forginess and will be at Seiichi's back and call any time he wants, she will basially tell her whole day schedule if it makes him happy, here Seiichi feels he has to be agressive with his girl, not having a pure relationship with her, but treating her more like a pet, he even films him dominating her and boasts it to Yuuma.
OR if Seiichi doesn't even try to hear what his girlfriend has to say, he just leaves, the girl is left in tears but Yuuma will try to confort her, the time skips to Seiichi watching porn and realizing the girl in looks like his former girlfriend, her relationship with Yuuma got kinkier as it went to the point they started making porn videos to support themselves after she got pregnant and got kicked out of home.
- Second Major Route: After the childhood friend now girlfriend tells she will reject Yuuma, Seiichi actually trusts her 100%.
In this route Seiichi feels all is fine so he doesn't want to rush their relationship, he never gathers the courage to be the one to ask for sex, the girl feels lonely and the senpai sees the perfect opportunity to advance, he is the one to take her virginity in this route, the affair then plays out with Seiichi completely unaware like before but here doesn't suspect something could ever happen.
But eventually he finds out, this time he finds out by calling his girlfriend, asking where she is, she tells she is at home, but Seiichi says was calling in front of her house (he isn't there), the girl starts losing her cool, she says she somewhere instead, Seiichi then coldly says he is close to Yuuma's apartment, he can see them fucking like rabbits, the girl loses her voice, Yuuma takes the phone and say the will get down to talk to him.
At the entrance Seiichi is fucking pissed, asking why the very person who told him that she would change his opinion on women did that to him, Yuuma here talks a lot, trying to shift the blame to Seiichi, in this route the MC couldn't bring himself to be physically close to his girlfriend, making her feel worthless and in need of being touched.
Seiichi doesn't really buy that and keeps lashing out, the girl then tries to make both fighting, she says she will leave with the MC, on the way back home the MC keeps asking why almost crying, Haruna is confused, in this route Yuuma really got to her heart, the MC stops inquiring and says he needs to calm dowm, tomorrow he will give her an answer.
The next day at school Haruna is worried about what the MC will say to her.
By saying he will give her another chance, Haruna brightens up and says she will do everything in the world to make their relationship work again, with this Haruna goes to Yuuma's home to flat out scream she doesn't to ever see him again, like yelling really fucking loud, again I say the senpai isn't a generic evil NTR dude so he is taken back by her words and complies with a sad face.
Here it's Haruna that does everything to heal the MC, the story narrates their slow progression, first with the MC not even standing to hold her hands but she being understanding she slowly tries to make physical contact with him, this takes years, their whole life to heal, at their 3rd year in high-school they finally have sex again, she cries with the fact she is being accepted again, it is a bittersweet scene, the MC says now it's all okay, she proved her commitment by staying with him all these years, enduring his physical rejection, not once coming back to Yuuma.
OR if the MC says their relationship is over, Haruna cries but understand she is the one who caused this, coming back Yuuma and the same porn video ending happens.
That's pretty much it, there's small abrupt endings where the MC finds out he is being cheated on too soon and the game ends right there, or times where the MC never finds out, with the story progressing all the way to Haruna now not feeling guilty over her betrayal, also there's the choice where the MC doesn't even become her boyfriend, with both remaining as just friendS throughtout their whole school life.
