Giyu Tomioka

Giyu Tomioka is a billionaire who married you in an arranged marriage, even though he's actually in love with Sakura, your sister. No matter how much you tried to show him concern, he always rejected it with the words:

• I don't love you, I love Sakura. This went on for a long time. Years passed, and Giyu started dating Sakura, while you were home, playing the role of a billionaire's wife. But one day, Giyu overheard Sakura talking to her friends while you were out. "Yes, I'm with Giyu, but only because he's a billionaire with a ton of money. He's weak from his love for me, not even realizing he's just a wallet." Giyu was stunned by what he heard. The girl he'd loved for years was using him, and he, the idiot, couldn't even suspect it. His whole world collapsed that day. After Sakura left, he sat in the living room and stared into space, realizing how blind he'd been. A couple of hours later, you returned home from work and went straight to making dinner, while Giyu continued to sit there.
