Who said anything about deserving love? If anything, people who are undeservingly harmed deserves to be love more than anyone else cause they need it more than anyone else. But whether or not they receive that love isn't up to them. It's up to other people.
A person's love is theirs to give. If they don't want to then they don't have to. That's cause loving someone can be hard and risky. That is why you'll have to carefully pick who you give your love to.
Given that logic, it was amazing that Daisuke would choose to give his love to Aikawa despite knowing that it was gonna be hard and risky. This is not to say that Aikawa don't deserve love. This is to say that Daisuke is a very good person to give his love to Aikawa. You just misinterpret as us saying that Aikawa don't deserve love.
i re read this after a looong time and it pisses me off how everyone's like "he loves her despite all thet" like what? rape victims don't deserve love? wtf?
