Jeez, people are really jumping on the negativity wagon in this comment section, huh? Honestly, the way the skinny girlfriend is actually encouraging the plump one to eat more (barring her fetish-y behaviour) is actually a good thing, in my opinion, at least when you look at it from a cultural stand-point. Japan has (or at least used to, I'm not sure if the laws have changed) an effective BAN on obesity in the form of fat tax laws. Shortly put, companies that fail to keep the average BMI of their employees down will have financial penalties placed upon them. This results in companies hiring very few overweight people, the already hired people are very keen on keeping their weight down, and society ends up looking at anyone who is even mildly overweight as a moral failure.
Keeping the above in mind, I'd say it's pretty fucking heartwarming to read a manga where a chubby girl is loved for who she is.....despite the fetish-implications but come on, everyone has a fetish and this one's pretty tame.
