Pete is a handsome and rich university student who is incredibly timid. His shyness stems from his trying to hide that he is gay. One day, Pete gets hit by a boy on a bike. The kind-hearted boy, named Ae, apologizes and helps him up.

In the past, those whom Pete trusted often used him for his wealth. Ae now steps in so Pete won’t be taken advantage of by his frenemies. Over time, Ae looks out for Pete and protects him from the world. Somewhere between their intense closeness and shared soft touches, Ae develops feelings for Pete that go beyond friendship.

Pete doesn't want Ae to know the pain of being ridiculed for dating a man, so he ignores his own feelings for Ae. But Pete falls deeper and deeper in love with the kind-hearted boy on the bike, who once hit him purely by chance.

Season 2 of Love By Chance premiered on September 1, 2020.

Growing up in a wealthy family, Tin had always enjoyed the privileges that inherently came with wealth. Never denied a thing, he had the world at his fingertips, yet his heart constantly reminded him that there were more important things in life than wealth and privilege. But with people using him as a means to better their own lives, he had little chance to explore the desire of his own heart. Suspicious of anyone who ever tried to get close, Tin had closed his heart off to the world, until the day he met Can.

An innocent and rather impressionable young man, Can had never met anyone quite like Tin. An incorruptible soul, Can’s sweetness left an indelible impression on Tin and their friendship blossomed overnight. However, as Tin and Can drew closer, Tin began to realize his feelings for his friend were quickly becoming much stronger than those of simple friendship.
