I don't know what you guys are on about takt is so obviously in love with shizuko, and its implied that he forced her to do the deed if you remember when MC and her were hiding behind the tree he said "she's been distant since that day" and then there's shizuko who's always regretting something in her monolouge "if i was going to do it anyway i should've done it sooner" and the end of chapter 13 "its already too.." what i interpret is she wishes had given MC her first
And takt always knew that's why he said i tried falling in love with someone else and despite knowing that that she loves MC he did that
This could fall into some of the cliches like she was in debt and he helped her in exchange for going out with him
Or she asking him to help her with MC but he does something and blackmail her
But i also can't completely dismiss the fact that he might actually be gay however i think it's unlikely
