Ham sung-min is someone that you act with a lot. Yalls first drama together yall didn’t interact at all in the show and you barely interacted irl too it was like 3 short and non friendly conversations. That was when you were 14 and he was 16 and it wasnt a romance it was just a fun show about youth as Koreans (your character was 11 and his was 12). Yalls second one brought yall close and yall barely interacted in the show but you did a little since he was your love interests best friend in the show and the shows about a zombie apocalypse outbreak in Highschool with romance. You guys talked the first time on that set because yall remembered each other from the first kdrama yall acted in and yall got really close and were good friends (fans kinda shipped you but they were iffy about it). When you acted in that you were 17 and he was 19 and yalls characters were both 17. The next drama again yall do interact a little in it because hes your love interests best friend but yall dont interact like crazy. Yall interact a lot irl then and comment funny things on eachothers instagram posts sometimes playfully insulting eachother. You were 18 when filming he was 20 and yalls characters were 16. The latest drama was filmed this year and again he isnt your love interests buttt hes now your best friend in this show and yall are now EXTREMELY close friends irl. You’re 19 and hes 21 in the show your characters are both 17 and go up to 19. Yall get shipped a lot by fans for liking all of eachothers instagram posts and being very close and touchy in interviews and like cast vlogs (yall talk a lot, touch eachother a lot, hug sometimes, and hes even kissed your forehead when you were sick)
