cast of thicker than water

When I turn 20, my grandfather's old friend—now the richest man in the country—lays out photos of his grandsons in front of me. He says, "Pick one to be your husband." Without hesitation, I choose Nathaniel Chapman. Everyone in the room is stunned. After all, it's no secret I've always been hopelessly in love with George Chapman. I used to swear I'd marry no one but him. In my previous life, I got what I wanted—I married George. And because of that marriage, he inherited the lion's share of his grandfather's wealth. But after the wedding, he started an affair with my sister. My parents were furious and sent her abroad to study. George thought I was the one who exposed them. From then on, he hated me to my very core. Women came and went at his side, each one resembling my sister more than the last. The betrayal crushed me. I fell into deep depression. Later, he secretly replaced my medication with slow-acting poison. I died with a child in my womb—alone, bitter, and betrayed. Now, I've been reborn. This time, I choose to let them have each other. But what I don't expect is that George has been reborn too.

Seungyoon, a freshman who enters college filled with dreams of a sweet, drama-like romance, falls in love at first sight the moment he meets Jihui, a girl from the same department. However, to Jihui, Seungyoon is practically invisible—so insignificant that she can’t even remember his name. The only men Jihui finds attractive exist inside BL webtoons. Real-life men don’t interest her at all, and she feels no romantic spark toward them. As the campus sweetheart, she has already rejected countless confessions from male students. Like the others, Seungyoon can only admire her from afar—until one day, he unexpectedly runs into Jihui in the department lounge. Watching her excitedly chat with BL characters on her laptop rather than acknowledging his presence, Seungyoon feels deeply hurt and makes an impulsive, drastic decision. “I… actually… I’m gay!” At that very moment, the classroom door swings open, and his words echo loudly— “Gay~~~!” Seungyoon accidentally comes out in front of everyone. Realizing there’s no turning back, Seungyoon quickly understands one thing: If you can’t avoid it, act it out—survival depends on it. With his childhood best friend Chanyoung, he ends up pretending to be a gay couple. Ironically, this makes Seungyoon the very type that catches Jihui’s attention. As they spend more time together, the once-invisible Seungyoon slowly begins to win her heart. But as Chanyoung continues the fake relationship to support Seungyoon’s love life, an unintended love triangle begins to form. With a lie that can no longer be undone, emotions intertwine, misunderstandings pile up, and deception breeds deception. How will this absurd and complicated triangle of lies and feelings finally come to an end?
