I don’t think either is toxic, I just think like you said, they both need to sit down and have a real heart-to-heart conversation about their relationship and future. They’ve never really done this before. Garam is naturally a very guarded person, especially after what happened with him in the past. Jaehyuk simply wants to please Garam and be the perfect boyfriend, but right now, they need to talk to clear the air and come clean about everything. This way, they can understand each other better and finally move forward together. They’ll get there though. I feel there is too much love between them.
Yeah, next chapter their relatioship will probably do a step forward ...
Garam to toxic sometimes (i mean J is always—yk, he really do everything for his babe) to much secret between them. And the communication is really bad, i mean this manhwa reach season 4 and the relationship just there and there
