Domestic Girlfriend/Domestic na Kanojo (Momo x depressed male OC reader x Rui)

This is a what if story. It takes place in the main time line but Ritsu Ousaka will never be a romance option. Author's Universe, I make the rules. Anyway, Momo is struggling with her day to day life even with Natsuo Fujii being the supportive friend he is. Some weeks later she meets a boy he recently transfered into her class. However, she wasn't the only one to notice him. Her friend Rui Tachibana also had her eyes set on him. Most likely not in a romantic way more of a protective kind of way. Momo is easily heart broken and delicate so of course Rui would worry about her. Find out more in the first chapter.
