The synopsis is basically the whole story. So the FMC suffers from a syndrome that makes her sick when she's super lonely. I know it's exaggerated but she basically faints if she feeks lonely. However before our kind and generic MMC took pity on her and decided to be her friend, she was alone all her life? So the question that came to my mind was, how was she surviving UNTIL NOW? Anyways our MC becomes friends with her, and it so happens that people start seeing her kind side and she made a few more friends. Typical SOL shenanigans happen, and there's no realstory.

The art was below average, and characters were extremely forgettable. Basically don't start reading this manga with expectations of ANY kind, and you'll do just fine.
