Based on how its translated it seems he didn't commit suicide but rather he's going to try to get revenge. The note however, he either wrote that incase the grandfather got a hold of it or haebom or just cause he doesnt feel worthy enough to be with Haebom anymore. Or maybe both. In any case after reading this chapter for myself I still have hope, which is stupid of me I know. I can't help it.
