RinRinRinB's manga / #Delinquent(3)

TW: sexual assault ? , borderline rape, rape (explanation below, contains minor spoilers) . . . Not really sure which trigger warnings to go for, since this is a usual omegaverse that starts off with forced seggs. MC's childhood friend knew he was in heat but keeps messing him up to the point MC had no choice but to accept said friend's s3xual advances. We see later MC *might* have feelings for childhood friend ML, but ML then used an aphrodisiac and I just really think this is forced. ML is manipulative that way. Just be warned.
