I've seen many a romance manga in my time and I have to say with the stuff that gets full series, this probably does deserve a serialization; if not for the kind of boring slice-of-life premise than for the medium-high level artstyle. Ngl my least favorite part was when she washed off the makeup and became stereotypical cute anime female lead. There's a sort of Hal Jordan/Green Lantern - Carrol Ferris dynamic possibly going on here that can potentially turn very frustrating and toxic if the male lead or female lead don't grow softer towards the other.
Where we end off, the onus is kind of on the male lead since he knows the "secret", and as the female lead continues to come back to see him maybe she starts talking about school and this annoying student council guy (him), which results in him giving answers that cause her to be a bit less hard on him (who is also the guy giving her the advice). The problem with this scenario is actually that the male lead knows who she is; there's a different ln adaptation manga somewhere around here where they both don't realize they are coworkers at their job and are giving one another advice about the other, and in that one there isn't a secret involved. In this one, there is and that's going to have to be addressed at some point with some drama involved for not telling the truth unless the female lead also finds out who the male lead is but doesn't reveal it to him. Oh now that's spicy.
Well I'm cooking way too hard for something that might never get serialized. Regardless I hope 米蔵 has a bright future, whoever that is.
