For those complaining about her weight change. Sigh, I'm actually surprised. I barely read this manga regularly, actually forgot about it until today when I was poking around and came across it. I decided to check out comments and I see some of you don't seem to understand that women gain weight when they're pregnant. Some faster than others, and of course, some more than others. Women's breasts also enlarge during pregnancy for milk and all that. So a woman with already overdeveloped breasts will get larger breasts. Some women who barely had a chest come away with busts that almost doubles or triples in size after pregnancy.
I jumped back to chapter 102 since someone said she looked slimmer in that chapter and didn't seem to understand how she gained weight in the next chapter. Just skimming gives you the answer. In chapter 102, it appears to be warm enough for her to simply wear a skirt and long sleeve shirt. In chapter 103 the weather has changed enough to force her to wear a coat with fur/cotton/whatever along the collar. This obviously indicates some time has passed which also indicates her pregnancy has progressed.
Even so, some women start putting on weight the moment they know they're pregnant. They get urges to eat food because they are now eating for two. As said, for some it happens slower, for some faster.
For those of you complaining about her massive bosom, I wonder if you've ever come across women like this in real life. They do exist. It always baffles me when a story or whatever chooses to focus on women with big this or big that and people complain because they want the usual slender woman without overdeveloped this or that. This is not an over-exaggeration of the author's imagination, women with large breasts and large buts exists and I'm not necessarily talking about fat ones, yet some people still consider that fat when their abdomens are taut and their waist is small. Go figure.
Just saying. I think some of you need to get out more and experience the world.
