Big Sister, Please Show Some Restraint!

The plot is quite good, but the male protagonist lives a very frustrated life and overly strengthens the people around him. The male protagonist is currently a very mediocre person, but this will make him very frustrated by the people around him, just like the part about the military training instructor. The male protagonist has no outstanding points. I hope he will grow up in the future.

Five-star praise (՞ਊ՞)👍👍👍
