Honestly you explained it better than the manhwa
Though I got the gist of it, this manhwa is kind of hard to read sometimes especially with the mixed up chapters. I think we need more backstory to understand them both better as well. Plus this whole USB thing just came out of nowhere, and now all of a sudden their past are connected. So I guess this isn't a simple love contract manhwa anymore and we're going to get more angst. Might wait for this to be complete before I continue reading, cause idk how happy a ending we'll get after all this drama.
