Chill out! It's just a manga. Most of the time you have to close your brain in things that are too good for your liking. To me it's a decent read and quite enjoyable. Also, in the story it was not officially mentioned that the senpai and mc are dating during highschool however, it was guess they were dating and mc didn't deny it and even ask Kouhei how did he know that. Also, mc is a very timid dude, we don't know if the senpai manipulate mc because most scenes in the manga mentioned senpai gaslighting mc. In the most part, don't overthink things (● ̄(エ) ̄●)

I don’t think courage had anything to do with the ukes prior relationships. At that point in high school his relationship with the senpai was just an exploration of his sexuality because it was likely easier to have a relationship with another gay guy than try to confess to the straight ml at the risk of ruining their friendship
Also, the seme fell in love with the uke in high school too and still went on to have a wife and kid. They both thought their love was unrequited in that time so neither one confessed.
That’s not the ukes fault and doesn’t mean that he whored himself out. You’re allowed to have relationships and sex with people if you’re not in a committed relationship and its mutual, which was the case for both the characters. Ultimately he didnt owe the seme his virginity and purity just because he liked him

Literally your right as if he needs permission to have sex with anyone or to explore his sexuality he wasn’t confident about confessing and turned to someone who understood him and would give him physically what he wanted to call him a whore for that is just insane this is legit normal human behavior sorry he didn’t wear white panties and keep his self clean for seme-sama all these years god some of yall need to seek reality
I couldn't enjoy this manga, I don't understand my old self for liking this before. Reading it now made me realized how stupid this manga is. Like, are you fucking kidding me? You went and slut your self out to someone you don't love back in highschool although you like someone else. And you go this guy touch you all over, and then years later he touched and even kissed you and you didn't have any problem with that??? Then the person you like went close to you and you say "you're too close".
Fucking idiot.
