Can someone...

what did you not get ? I'll try to help you

Everything that happened after the neighbor confronted them. Thank you so muuuuccch

oh ok so basically everyone is a fucking psychopath and yandere asf.

KANAO : Ever since he was little he was compared to his older brother Kaoru and was always scolded because he wasn't good enough by his dad. One time after being hit by his dad, he saw his older brother and his dad being intimate with each other in a room he accidentally walked into and came up with the conclusion that he too wanted someone to love and to show off to other people how much he's being loved (that's where his addiction to having sex outdoors and stuff comees from). He met Sei and sort of loved and used him after they first met and then when he found out that he and Sei weren't going to the same university and Sei said to him "I hope we can find new friends and girlfriends" Kanao became a bit yandere and purposely did bad in his exams so he can go to the same Uni as Sei and thought that the only way to tie Sei to him was having sex and making him fall in love with Kanao. After they got found out by the neighbour and Sei said to Kanao that they're only sex friends Kanao used the neighbour to try and make Sei jealous by hanging out and stuff, but in exchange he knew and allowed to neighbour to keep stalking him basically and even placed cameras in their apartment so the neighbour can watch. By not wanting to have sex outdoors like usual lead Sei to think Kanao and the neighbour were having sex too -> got jealous -> realised his feeling and love for Kanao -> heard Kanao next door pleading for help and ended up founding out that the neighbour stalks Kanao and then he 'saves' Kanao, brought him to a hotel and confesses his feelings to Kanao -> they have sex as a couple -> after Sei asks if they want to report the neighbour to the police but Kanao obviously said no -> *timeskip* they moved to a new house/apartment, have sex at the door then Sei leaves for school -> we then see Kanao leave the house and find out he's still meeting the neighbour and that's when we found out about everything (what I previously wrote) they talk and then finished with the conversation with the neighbour still allowed to stalk Kanao and watch him and Sei having sex -> Kanao comes home to Sei cooking dinner but interrupts him and asks to have sex in bed -> they have sex in bed and the alarm clock is put into focus showing us there's a camera on it (that's how the neighbour continues to watch them and Kanao's fetish of someone watching is satisfied) -> finished sex with Kanao saying "I love you" and shit with Sei saying "I love you, too. Whatever you are....whatever happens....I'll always love you" END the story with us thinking Sei is the only normal one in the story. WRONG.

SEI : The side story comes on and Kanao and Sei seems to have gone on holiday, they're having sex on the beach -> then we see the neighbour at work or something bump into someone, (we can identify him as Kanao's older brother Kaoru) immediately falling in love -> cut back to Sei and Kanao still having sex on the beach -> they finish and then Sei says "It's.....nice being alone" (ME : AAAAHHHHH) Kanao is confused and says "huh?" and Sei replies with "Don't you think so?", interrupting what Kanao was about to say, Sei kisses him, then the background repeats what Sei previously said - No matter what you are...I'll love you - so basically Sei KNEW that Kanao and the neighbour were sort of working together and that the neighbour is always watching -> then Sei's phone *BRRR BRRR* getting a text, we see the content of the text, it's from KAORU a.k.a Kanao's OLDER BROTHER, the text says "I met the guy. He seems interesting. I like him. Thank you for contacting me. Don't tell Kanao any of this" -> in a thought bubble of Sei - ...I will...keep you....forever mine.... Kanao - Side Story END. We can assume that because Sei knew everything and accepted Kanao for the perverted psychopath he is but is still not ok with the neighbour watching them have sex cause he wants to keep Kanao to himself, devises a plan to take away the neighbours attention by contacting Kaoru to entertain the neighbour and stuff :)
