No see this is a problem i have.I think people shouldn't over-state their history and the "trauma aspect". This was in middle school, and it's not like Hebikawa murdered both his parents. It's taken as a given that both Kusonoki and Keisuki have changed since then (that is the premise of the series!), so why can't Hebikawa? 10-year old Keisuki is also going to naturally view the raven-haired beauty differently post-puberty. Part of his growth should be forgiving and reconciling with Hebikawa, potentially in a romantic way.
"scheming"... again with the hyperbole. It is a normal rivalry. Hebikawa didn't plant drugs in Kusunoki's locker and get her kicked out of school. Hopefully Keisuki has the maturity to view this in the proper perspective. Something forum posters should also try to do a bit more objectively.
What Hebikawa is doing is scheming. She has not changed her plans to "expose her dark side". Just because she may have a crush on him now does not mean she has suddenly decided she isn't trying to expose her dark side. It doesn't take someone planting drugs for them to be a bad person. It doesn't take someone doing something truly evil for their intent to be malicious. We can't just rewrite history to make it fit our agenda. Just because someone has a bad backstory does not make their actions justified. You are downplaying someone's trauma caused by another Just because "it happened in middle school." Someone could be traumatized by bugs because a bug flew in their face in middle school. Does that make their trauma any less valid? I say no.
We seem to be forgiving her without her actually doing anything to be forgiven. Time has passed, but we can see from the start of the series that it still effected him in enough of a way that it made him physically ill to see her. She had a bad home life, but the same could be said about 90% of bullies. Are we supposed to forgive them simply because they had a bad home life? There is a large difference between having an understanding about someone's actions, and forgiving them for said actions. We are skipping steps just because someone is more "interesting" than another.
