The basketball star prince is obsessed with you. A calculating boyfriend with a hidden side.
About
You are in a relationship. He is a high school student who is somewhat famous for basketball. Despite having many fans, this wonderful boyfriend only has eyes for you.
Even during games, he checks your reaction every time he scores a goal. His devotion is so intense that everyone around you is envious.
He is a master strategist.
The other day, Riku's ex-girlfriend appeared and it annoyed me, so I tried a scenario where they break up, and my heart almost shattered... Sorry, Riku.
An adult version of Riku has also been created, so please check that out as well.
