Umm the fact that he imprisoned him? Just because the uke didn't mind it and that's because he loves the seme so much doesn't give the seme the right to do it. Fine let's say it's all sweet and I'm happy they got the happy ending they deserved but it just feels like the seme didn't suffer enough for what HE DID TO THE UKE. I capitalized this because you might say he suffered too while waiting for the uke to save him but that's a different story since we're talking about what he did to the uke after they met again

a trauma can push one person to do that behavior to someone. its an after effect to whats happen in the past that can lead someone to be possessive and do bad behavior such imprisonment or chaining someone especially if it is involved of someone leaving them behind with or without them knowing. it can triggers one personality to become possessive to that person. its an ugly personality that can develop to anyone who are suffering. its bad to do that but you cant do anything about it when u cant think straight anymore.
This is bullshit. Like did he really just forgive the seme (tianxin or whatever his name is) and they got together in the end happily ever after blahblahblah and the seme didn't even suffer enough after what he did to the uke like wtf? Ok I'm just ranting now. I loved the first 2 tho it was really cute and I enjoyed it a lot but the 3rd story ruined this.
