Everyday is a struggle with Ryu Sun Jae because he is a simp. He was born to teach us what an absolute pleasure it is to watch a man simp so hard that he needs a moment to look away and compose himself so that his downbad smile is not on display.
Downbadism is an art and Byun Woo Seok acts like he did a four year degree on it. You go king.
Another thing that absolutely is adorable is that Im Sol is still not in love with Sun Jae. Everything she does is out of the love she has for a person who got her through a hard time, someone she has grown to care about but as an idol. Right now while she has begun to see Sun Jae as the kid who lives next door, it is still her idol that she wants to save. And that to me is pretty nice because she isn't trying to impose herself on him or his life for any other reason but to keep him safe. There is no ulterior motive. And I think thats what makes her so likeable.
Special mention to tae sung, he is adorable in a way that not all second leads are and all his scenes with his banter with Sol are extremely fun to watch. In another drama, they would make an absolutely cute pair. They make a cute pair here too ngl. Love how she treats him like a naughty child and he calls her grandma
