I remember when my brother showed me this manwha in high-school, it had about 30 or so chapters, I loved it, read it till it was completed (with a few hiatus) and recently thought about reading it over again, ended up recommending it to a few friends, they all think it's a bit sad, but awesome. I would 100% say read it, it meant alot to me as a kid, and I think it could teach some decent life lessons ngl.
