By Chance, By Heart (บังเอิญรัก...ด้วยหัวใจ) (JimmySea)

Sea is a dedicated university student who wants nothing more than to focus on his studies and achieve good grades. However, his family has different ideas. They constantly try to set him up on dates, hoping he'll find a "nice boy." Sea is exhausted by the relentless matchmaking and awkward dinners. All he wants is for them to stop bothering him so he can concentrate on school.

His best friend, May, suggests a bold plan. What if Sea hired someone to pretend to be his boyfriend? If his family thinks he's already in a relationship, they might finally leave him alone! At first, Sea thinks this idea is crazy, but he's desperate for some peace.

That's when he meets Jimmy. Jimmy is a struggling actor always on the lookout for his next gig. He's funny, and a bit dramatic. He needs money, so when Sea explains the plan-pretending to be his boyfriend to stop the family pressure-Jimmy smiles. Acting like a loving boyfriend for a few weeks? Easy! He's played weirder roles before, like trees and ghosts. They strike a deal: Jimmy will be Sea's fake boyfriend, and Sea will finally get his family off his back.

Their pretend romance begins on campus. Jimmy dives into the role with excitement. He holds Sea's hand in public, gives him cute nicknames, and acts like they're madly in love. Sea often feels embarrassed by Jimmy's dramatic performances and asks him to tone it down, but Jimmy just winks, saying they need to be convincing for Sea's family. This leads to many funny and sweet moments as they try to act like a real couple while balancing their studies.

As they spend more time together, something unexpected happens. Their pretend walks and shared lunches start to feel real. Sea finds himself laughing at Jimmy's antics, and Jimmy enjoys making Sea smile. The lines between acting and reality blur, and they both begin to wonder if their fake relationship could turn into something genuine. They must navigate their secrets, studies, and the surprising feelings growing between them.
