What Is Thunder Cloud Rain Storm About?
The plot follows Lee Il-jo, an illegitimate son who finds himself at rock bottom with no money, no job, and no home after being mistreated by his half-brother at their father’s funeral. Desperate and vulnerable, Il-jo turns to his cousin Seo Jeong-han, whom he hasn’t seen in years.
Jeong-han offers Il-jo a place to stay, but their living arrangement takes a dramatic turn when a drunk Jeong-han impulsively kisses Il-jo one night. Things get even more complicated when Il-jo is hospitalized with gallstones, and Jeong-han pays the 4 million won surgery fee, then presents a controversial contract demanding Il-jo “repay it with his body”.
The contract essentially binds Il-jo to Jeong-han’s home and states that all of Il-jo’s rights belong to him. What starts as a power-imbalanced arrangement slowly evolves into something deeper as Il-jo’s innocence and desperate loyalty begin to influence the initially indifferent Jeong-han, drawing them into a complicated and messy connection.
Meet the Cast
Yoon Ji-sung as Lee Il-jo: The former Wanna One leader and solo artist brings heartfelt vulnerability to his first BL role. Known for his work in Let Me Be Your Knight and musicals like Something Rotten!, Ji-sung’s emotional depth makes him perfect for this complex character.
Jeong Ri-u as Seo Jeong-han: Playing the cold, possessive cousin whose walls slowly crumble, Jeong Ri-u delivers the perfect counterbalance to Ji-sung’s innocence.
The chemistry between these two leads has already generated buzz from the trailer, which showcases intense emotional moments, physical conflict, and undeniable tension.
