I agree. Her friend actually "broke up" their friendship in a very mature way. Stated why with no blaming, and set boundaries. Pretty surprising for someone their age.
Remember, nobody owes you their friendship or time. Just like in a romantic relationship, people are in their right and...
Damn who would've figured that "I'll wait for you" for Gen, when I was wanting Reiji to forget about everyone and leave the town, was actually Reiji's final saving grace. Now he has nothing to hold onto except go through with the murder.
It's a bad thing because this innocent dude doesn't deserve to go to prison for killing a scumbag. His poor wife will also be alone with him being in prison, making that scumbag impact her further and ruining her. I can understand the feeling tho.
