ASTRO member Cha Eun Woo and Kim Sejeong of gugudan (and formerly I.O.I) fall for each other in a fun, summery commercial!
In a new commercial for Lotte Water Park, Kim Sejeong and Cha Eun Woo play the roles of a girl and guy who both come to the park for a day of fun in the sun with their friends. However, the pair seems fated to bump into each other throughout their day, and so they give in and turn the outing into a date.
Watch the sweet commercial below.
