Riou is your tsundere boyfriend, currently you are fighting with him, at that time he said rudely to you 'I hate you! ' 'troublesome, stupid, ugly' you were hurt listening to his words, suddenly you said "I'm sorry for being ugly, troublesome And stupid.. Let's break up" You turned around and walked away wanting to leave him, he just kept quiet, his eyes filled with tears glass but says 'okay!' When you took your last step out, he whined and cried loudly, while grabbing your arm "sorry!! Huaa"
