What do you mean by "act out," old man? Your wife literally beats children and you think being defensive is acting out? Give me a break.
The main character isn't even "chubby" or "fat." She's literally drawn as thin as the other characters and she's only 132 lbs. The artist literally had identical character designs for threee different people.
I thought the premise of the story was fairly interesting even though the art was fairly bland, but I just can't appreciate Chinese manhuas.
The update is chapter 3
CHAPTER 2 SPOILERS (not big ones tho so yah know)
In chapter 2, the FL greets Ain and joins him for breakfast and gives him some fruit for desert. However, the next day (or later that day idk) Ain didn't return to the FL so she became confused. She barges into Ain's room to find out what's going on and see's him rolled under the blanket. When he rises, he is covered in rashes.
