Makoto was two years old when his mom moved in to stepdad, but didn't remember he had a year old sister? This is such an asspull...
Aizawa hating her mom for abandoning her is reasonable, but then regretted that and tried hard to be with her up to even neglecting her health, sure some resentment should be but calling her "hag"...
Makoto on the other hand also was abandoned, but don't think she simply ran away to Aizawa and then it got bad with Shiori father...
Makoto ruining the situation when he tore up the letter, still blaming his mom for all the issues is moronic at best...
Wasn't the inspector arrested after being framed for murderer of Makoto father, how did he escaped?!?
