Chen got rejected in the game, but she remained strong.
sorry for the necro but since TokiMemo got an ENG patch now so forgive me
this scene is just one of many scenes where the protag tries to ask the girl to go home from school with him, and Shiori will rejects him if her "Like" stats are neutral/negative towards you
some girls will accept your invitation even if it's neutral, but Shiori, being the hardest girl to get in the series will only accepts it when her "Like" status are positive
Oh, are you playing Tokimeki Memorial, Chen?tremble tremble trembleCheeee!Uh, um? I'm sor...You've grown so strong, Chen!I'm sorry. If we walk home together, people would talk and that'd be embarrassing...Tears of Joy
