@Yatogami Firstly he once went back to save her so it's only right that her repay the favor or she could have at least told the others that she saw him then and there but no she waited untilthey had full escape to bring up the fact that she saw him. Yes they probably wouldn't have gone back but she could have at least tried. Secondly if he tried to help his friend he would have died as well.
@Tae Sis there were monsters after them,she was running for her life,it was no time for a group meeting. She realised that it might be too late for him because brother was stuck in a building full of monsters and moved on. What was she supposed to do? Tell others to go back to save him and get others who might have escaped killed too? Use some common sense,everyone is responsible for their own lives and it's not like anyone asked or forced the mc to save the girl. He ran out on his own knowing he is risking his life and if you do such stuff without consulting with anyone or telling anyone your plan no one is expected to pay you back. It's just like forcing your feelings on others,doing something for them knowing they never accepted your feeling expecting return.If he told them his plan I would get it too but he didn't,they were not supposed to wait for him.
@Tae Like anyone who would be so petty about it later should not risk their lives for others in the first place ,nor did anyone ask him too. So he could just accept that what he did was foolish and make his priority to get back together rather than being so bitchy about it. Was the girl supposed to say sorry for putting her own life first? For a classmate she talked with for the first time that day? or survive for her family and people she actually deeply cares for? Also the girl wasn't even rude about it,she genuinely felt sorry ,she is a nice girl and the mc is an ass**** for making her guilty for something that was his own decision to begin with.
