The Little Sweet Cutie Always Think That He Is a Stand-in Chapter -- Discussion

Idk why some people hate MC? He is literally mentally ret*rd...I means, mentally unable to mental any sht. Cant blame him for being s*upid and ret*rd. Loll

First chapter already give hint that he has weird sht going inside his brain. I also pity ML. Some people didn't see a whole picture of his good deed. He trying to work all the effort to take MC but only observant eyes truly see it.
