I can't take it anymore, how devastated toshi when he realized all the things he did wrong. But toshi had an option not to kill himself, maybe he saw that there was no redemption for him and what he did wrong. The chapter 7 made me sad that toshi really cared about ryuu, it's just that he let the monster take over his reasons that made him do those things to ryuu. And the person who understands him and stayed with him, itsuki felt betrayed that toshi died without even thinking what would the people who care about him would feel. Itsuki and ryuu's drugs is toshi which represents their freedom, that's why i understand that they did those things to be free, to start again putting toshi in the past. And learning to properly love someone, i think they already have chemistry though. Maneyama is a good person, to be able to pull itsyki back to reality and facing life. I honestly thought that toshi is still alive, and it turns out that it was just a flashback
I seriously felt no romance attached, and if there is, i think it was one-sided (only bb sam) it's a good webtoon, but i think there could be improvements in the plot.
