yeonseuls a pretty obsessive type of guy but not that kind of obsessed which is bad/anything, he's just the kind of someone who's jealous and clingy but in a positive way. There are people that got easily jealous/possessive but not everyone could control/maintain their feelings like him
it's just that he cherishes his first real relationship so much that it impress me that he actually could replace his (hugs) jealousy and ego with love instead of doing something like "angry segs or jealousy segs" which i don't really like lol. I really like his character & how he keeps his relationship healthy!! And of course, he tries to communicate even if not everytime but through little things too😞💗
At times where there's a love rival and the other got jealous, there's usually a scene where they misunderstood/just act egoistic like forcing the other to segs or submit to him and stuff. I dislike that lol but I've seen it a LOT in bl manhwas
