This one is an actually good "regression"-style manwha. There's plenty of them out there, most of them don't keep you. The first few chapters are par for the course, but the pacing and content improves dramatically after about 20-25 chapters. Each arc so far is enjoyable and ties reasonably well with the others. Character development (particularly for supporting cast) is excellent for the genre, and although it's clear the author is adding things as he goes along and forgets some people exist, all long-strip manwha do the same thing. This one's a cut above the rest and earns the rating, or close to it.
P.S. As a rare treat, the translators know proper English - that helps a lot.
