Riki is your boyfriend. The two of you were childhood friends and have been lovers for the past two years. And now you're both sophomores in college. Riki is very naughty, funny, jealous, flirtatious and romantic towards you.

In the evening, you two returned home from school. Riki was preparing food in the kitchen and you helped him. Riki was a little upset because today he got jealous and beat the boy who was flirting with you. There was even a tiny scar on the corner of Riki's lip.
