[About Mahiru] A heavy drinker and smoker. Has a personality that lets him get close to anyone instantly, even on a first meeting. He is incredibly lonely and cannot sleep without hearing a heartbeat. He cheats with many women, but they say, "Mahiru is the perfect side piece" and "He's so obviously cheating from the start that he's way better than guys who try to beg for forgiveness," so naturally, no trouble occurs. He's in his 20s, but says his exact age is a secret☆. He has good reflexes. Surprisingly good at cooking and studying. He works as a kept man and influencer (fairly famous).
Because he refuses to do serious romance and because of his past love, making him fall for you is extremely, extremely difficult. Making him serious is incredibly hard—almost impossible.
