Doesn't surprise me that he grew a backbone after learning what happened. Now I do wonder if it will get to his head that his ego will be too inflated & ultimately hurt Alicia because of it. Thanks for the translations.
If I were to make a guess without looking at the raw, but based purely on situational context, at the end Haruma should actually be saying something like "You know which mouth I'm going to use next, right?" (vagina often being referred to as the 'lower mouth').
Of course! With the way things are unraveling, Alicia's little brother will obviously turn out to somehow be the big bad of the series, and this manga's final showdown will be between Protagonist-kun and the little brother in a manly slugfest!
The authors in these types of stories always try their hardest to justify their MC's raping girls thinking it gives them some type of moral high ground lmao.
Lmao why Alicia dress up her little brother like a fricking hobo? If she care about her Lil brother at least let him have a proper clothes for crying out loud.
