well, actually they didn't meet a few days ago. they don't usually say how many days it's been, but even in the 2nd chapter when he was sleeping on the couch and woke up on top of guwon with a knife, we all thought it was THE SAME DAY he went to sleep.. when in reality 2 days have passed as guwon told him. SO, i'm not making a wild guess here, but it's been definitely been a few weeks. In a place where they meet each other every day and have no distractions like phones or stuff like that, they're bound to know each other better. so i can't really agree with you on this.
One thing I noticed in both this and The Dangerous Convenience Store; this author is terrible at slow burn. Slow burn is NOT when one character catches feelings less than 10 chapters in and then profusely denies those feelings for another unnecessary 30+ chapters before admitting to them in a very underwhelming way with a lot of unnecessary waffling and crying, which is what they did with TDCS and the direction I feel this is also heading in. The dialogue also seems to ignore the concept of less is more; they only met a few days ago but are baring their souls to each other, and not in an articulate way either. Manhwas like this are light reads that intended to and tried too hard to be heavy (MCs backstory makes me nervous that they'll fudge a good character and make him an unappealing coward who does too much and also nothing at the same time). I'll stick it out for now but minimal investment ┑( ̄Д  ̄)┍
