So after finishing this I must say that I did indeed like it more than "Hakwonmul" but at the same time, it's still not the best. It is a truly cute story and I liked all the characters but some of the situations are grating.
I personally liked Jaehyuk and Taehyun the best as characters. The former may be a yandere douche who has too many similarities with a rl abusive BF but at the same time, he felt real in that he was twisted up inside and knew what he was doing was wrong...but couldn't make himself stop (too weak willed?).
Taehyun is the best character. He's kind, selfless, works hard to do what he thinks is best for his family but is also an unknown-aged man living in a body at least 20 years younger than normal. This would bring some concerns to the more sensitive readers since it means a grown man is basically crushing on a teen.
All that aside, it was worth a night to read it. I recommend 6.5/10
I am really liking this so far (got to ch 12 at this time) and I know from comments that the story feels rushed and ends "meh" but right now, I'm just enjoying the ride. This is already way more put together than "Hakwonmul", the author's other title imo.
