You know, i've been having this feeling that something bad is going to happen to either Hori or Miyamura. But it's not that kind of manga so maybe i'm looking too much into it ?
Doing nothing all day, then feeling bad that you did nothing at the end of the day. It's a never ending cycle. One way to get out of it is to force yourself to do something else to break the habit. It's hard, but such is life.
