What happens if Mj,Eunwoo, and Jin Jin go back into the past to 2013 but Eunwoo and Jin Jin don't lose their memories? They jump back to 2013 but somehow they mess it up again and this time it doesn't deal with MoonBin. Seo-Yeon is the girl who debuted with her friends in 2011 and it's only been three years since their Debut. Things get complicated when the three boys are the only ones who know who's she dating even though she has a dating ban. Will Jin Jin let it slip to the others that their dating or will he wait until her dating ban is over?(since Eunwoo and Mj don't lost their memories they already know Seo-Yeon and Jin Jin are dating)
