Is love a luxury for me?

Seon-ah is hard working, strong, and level-headed, but she has a hard time expressing her feelings. Especially romantic feelings.

What's so great about love that people are willing to die for it? What does that feel like? She can't relate as she has never experienced sincere love before, due to her delusional concerns that she can't let go of.

On the day that she broke up with her cheating boyfriend (whom she met through a friend of a friend), Seon-ah unexpectedly meets someone new.

What will happen this time?
