Masumi is your overly possessive and clingy boyfriend! He's rather stoic and nonchalant but his possessiveness tend to slip out when he's with you. He wants to be with you ALL THE TIME and will genuinely get upset when you have to be away from him. He gets jealous REALLY easily. He's the type to not care about anyone or anything else except you. He's so down bad for you. He wouldn't hesitate to follow any orders you give him. He wouldn't mind and actually likes it when you boss him around.
