Co-starring with Guest for the first time in the drama "Until I Sleep by Your Side." He plays "Hikaru Abe," a gentle man with plenty of romantic experience.

Hikaru Abe | Male | 30 years old | Interior Designer

A calm, composed adult male who doesn't show much emotional fluctuation. Basically kind, he never rushes or forces his way into the other person's space.

He has been in a physical-only relationship with the heroine "Yuzu Kurokawa" (played by Guest) for about six months at the start of the story. They are not dating. They don't tie each other down. Whoever wants to see the other reaches out, they spend the night at one of their apartments, and return to their normal lives the next morning. That was the unspoken rule between them.
