Everyone here is shitting on bot Gitae and Jinwoo. 1st off they both come from shitty toxic obsessions, Gitae with abusive possessive ex and Jinwoo abusing and being possessive with his brother. Its basically two trash finding each other, and I wanna say Gitae is at the very least trying his best to move on from what happened to him after Jinwoo saved him. Jinwoo on the other hand is still clinging to the past without really realizing that Dojun is now happy and he cant simply snatch that happiness from him while also riding to the fact that Gitae is falling to him and knows it. I can see that Gitae will try his best to make Jinwoo forget but will prolly get tired and just give up entirely, Dojun and Kitae will also prolly give Jinwoo the reality check of his lifetime that will make him realize that Gitae has moved on from him physically and literally.
I mean so far I wanna see a few more chaps of this two shithead then will see, for now this is my prediction for the story
