Yeongwoon is thinking that. Seo in is confusing him when he continues to change his behavior acting cold most times, and sometimes sweet, so when he’s sweet he can’t help giving into Seo in..
Seo in has provoked him on several occasions, one example-telling him to leave if he doesn’t want to go ahead with sex, but Seo in knows he won’t (I also see it as him being manipulative, you can also debate that he’s actually giving him a chance to walk away), this chapter he’s saying ‘is that the way to talk to a friend, ask properly’ that’s provoking and confusing him… his response is confrontational and designed to escalate the situation… YW might be referring to Seo in’s kind look during that sex scene.
he gives him gifts when he’s being sweet-jacket, necklace, doing his hair (I will need to read again later when he was actually sweet, which I think was rare) …in this chapter he did apologize… that could be sweet and surprising to Yeongwoon.
One question the POV in chap 29 during the sex scene whose was it the ML or Mc ??
