Global Fog: I Mass-Produce Ability Fruits

The eldest lady in Beijing and the protagonist are boyfriend and girlfriend. After their graduation thesis was cut off and they broke up, they took three roommates to insult the protagonist. I found that the protagonist's attitude changed 180 degrees after awakening, and then she went back to talk to her grandfather about the matter. (Looking at the conversation, she seemed to like the protagonist again) After returning to the protagonist's dormitory, she knocked out her roommate. He also sealed up the male protagonist's waist to prevent him from getting involved in sex outside. [What] 😅 If you want to read it, go and read it. Anyway, I will comment after Chapter 6. I don't know what will happen next.

You can produce some partially metalized fruits that can fight and prevent movement.
