But if you think about it, what could he use to threaten him?? Haebom doesn't even have a family of his own, he just had his parents who passed away... His family is basically Taesung's family since his mother adopted him, and I don't think the grandfather would threaten to harm his own daughter and grandson... This just doesn't make sense, and even if he did threaten him in some way, you don't just run away like that without leaving a trace, keep living as if nothing happened and leaving your boyfriend behind like that knowing he's surely suffering a lot because of your disappearance! Whatever the reason that's just cruel!!
I admit that the author is using this manhwa for the money,but think about it in another perspective. There is a plot hole about taesung’s family. Maybe it is hard for ppl to accept this whole situation bcs cbaw is most definitely not angst but now suddenly it is. If it wasn’t angst then the new season won’t get as much hype as it did now.
Personally for me,i love angst so im not complaining about this whole breakup and kidnapping plot
I'm not saying he is not suffering in his own way, but he should have talked to Taesung about it properly, whatever it was, they could have faced it together! He is his boyfriend and his family, not some random acquaintance! Taesung deserved to know. It must be a real nightmare if someone you love suddenly disappears into thin air for months and you don't even know if they're dead or alive... At least he could leave some message since it doesn't seem like he is being held captive or he lost his memory!

I don’t get why everyone hating on the new arc the author is just filling in the plot hole from previous seasons,like taesung is from wealthy businessman family obviously the grandpa won’t let them be
And people who blame haebom for breaking up with taesung don’t use their brain at all,obviously he was threatened by that grandpa
