So the fl and ml is both blonde I think.
It started when the fl returned to the past and planned to save the ml because if the ml dies she will die a couple of weeks after the ml died. In the present timeline both succeed in to living past the age they both died but then the ml leaves and returned pretending to be someone else and they're both student in a magic school I think

My friend, you're not an idiot for having empathy.
