I personally think it would end soon, I just hope it would end soon enough before I lose my interest in it because it's dragging a little too much xD.
The relationships between all three have set up pretty nicely already, SejuxSumin has warmed up to each other, SuminxSungji is very happy about their relationship. It's already a perfect set up for some final grand drama xD. Of course, we can't keep this current routine between three characters with Sumin running back and forth with Seju and Sungji, we wont be able to see the ending with this. There would be sth happening to break this dynamic. And once it happens, I believe the ending wont be that far xD. But I hope it wont be dragged out alot by adding unnecessary sex scenes xD but it has to happen for the sake of fan-service so well.... xD
Well, SejuxSungji's head-to-head situation is sth I'll pay intention more if there are some more interactions between them in the next few chaps. This chap makes me wonder a few things. in chap 79, I thought Sungji has striked sth to Seju or at least has one head higher than her, but this chap has proved me wrong, Seju is completely unfazed by those words. She even found it funny, even think it's funnier that she got permission to stay in the house and told that to Sumin. I find this particular conversation between Sumin and Seju weird, from both sides. I'm not talking about the Seju's honesty. Why does Seju find it funny that she got permission from Sungji to stay? And when she said it, why is there no reaction from Sumin? Clearly, Sungji only texted Sumin and told her about her decision without telling her that she had lunch with Seju, she hid it and Sumin only found out later when Seju honestly talked about it and find it funny #_#. This conversation is weird in my book but well, I might over-react and maybe because I haven't seen these kind of reactions for this situation anywhere but here =))))).
