Yeesh... Not Yukiko's finest work, for sure...I guess she wanted to show a "realistic" view of what being a model is like, but damn was that bad. Like, I've seen news about stuff creeps in Japan get up to and it's pretty horrible, but a transphobic trope is still a transphobic trope and perpetuates transphobic ideas, so maybe next time have the creep be creepy without, you know, implied transness?
And about the weight... 42kg? Makes me think of many 90s models in the west, who were anorexic or were in the verge of it... Japanese women might be shorter, but I doubt it's enough to justify an adult having the weight of a child.
So, overall, pretty bad. There were some cute moments here and there, I doubt Yuma was just looking for friend at the beginning and the way she tried to build a relationship there was nice (even if it's only a personal headcanon). I think Yukiko might want to focus on that kind of feel-good stories, she has more experience with that than, well, this kind of drama.
