LOL this is hilarious. Certain parts remind me of Ouran High School Host Club, the ridiculous exaggerated depiction of rich people and just how unaware but also sweet our ML is. (Tamaki vibes)
Not the biggest fan of female MCs who are timid from trauma (I don't mean I'm not sympathetic towards them), especially because most of the time this becomes a precedent for conflict/misunderstandings that can been resolved simply from communicating but we'll see how the manga takes it from here.
