I said it last? chapter, series has also portrayed the childhood friend negatively when it comes to their mentality. Although, I will say, MC is an absolute retard. Not because he didn't fuck her, but how do you go from "he confessed to me" to thinking she's in love with someone else? Wouldn't she have just said "yes" to the confession?
Evil me thoughts
MC shoulda fucked her though, and then his sister afterward. Maybe have the sister suck him off after fucking the childhood friend? Best ending would be a threesome.
Thanks for the TL btw
