I honestly think this is grooming. Like you can be groomed as a young adult and you don't know. Especially if its by an older man. Even though we don't know the seme age it still off putting how he fell in love with a child when he is obviously older than him. The youngest he is would be a teenager.
I LOVE THIS TYPE OF STORY!! Its so messssyy and its such a rollercoaster of emotions while reading it. I really liked the mc she was really funny and relateable. btw are we gonna forget ono was sleeping with tomoya mom????? like she is a predator!! the way she acted around her own son!?! She made the story hard to read.
