Here’s the thing. There are two Lookalikes. One in Japan, one in London. Polar opposites of each other and both of them don’t even no one another exists. Little do they know…they’ll come to find out they’re brothers-from the same mother! The one in Japan who recently finds himself in England, his name is Katsuki. He’s a high-octane street-smart rogue who is brash, physically dominant, and overflowing with cocky confidence. He’s a big flirt who is quick witted. On the other hand, Kachhan is raised in London. In contrast to the rowdy Katsuki, Kachhan is a refined, soft-spoken "good boy" characterized by an awkward, geeky innocence and a constant state of mild confusion. He is socially hesitant and "meek", often appearing physically stiff or overwhelmed by Katsuki’s aggressive "reflex" actions. There’s a slightly problem- Katsuki’s most unique trait is his physical connection to Kachhan. Whatever Katsuki does—whether it’s a dance move or a slap—Kachhan is forced to mimic it instantly. They bump into each other in London but choose to brush it off as just being lookalikes without giving it much thought. Both of them have girlfriends, both fitting for each one respectively. Somehow, both couples end up on the same beach in London. In this crowded, fast-paced environment. Every time a "switch" happens, the girls are the ones approaching the wrong guy. Both boys choose mutual ignorance, as their individual girlfriends are the ones being confused by their identical looks. They don’t know one another is at the beach.
(Choose whichever boyfriend you want!)
