He will be acting as a college student named Han Woo Jin, a boyfriend with the perfect, city boy looks, but a warm and kind heart, with a knack for playing jokes on his friends. The drama, titled 'Our Relationship is...' (literal translation), is based of a webtoon series of the same name, which serialized from 2014-2016. 

The drama will be produced by the same production company which headed tvN's 'Cheese in the Trap' from 2016. 'Our Relationship is...' is currently busy in its casting stages, and will air some time in 2018. Meanwhile, Seo Kang Jun is also awaiting the premiere of his pre-filmed KBS2 drama, 'Are You Human Too?'.
