tbh i'd have been after makoto at that age, she's just my type. even if my adoptive sister had some kind of crush on me. the weirdness would still have hit too hard.
edit: finished chapter. nope. sister is wife fugg everything lol
been in anogahara's shoes pretty much verbatim. older bro(not older sis) told me i was a fuck up for hitting on his little sis though, disowned me. irl is ass.
