Since their debut this August, Miyu, Byeol, and Nari have all had a birthday! Miyu and Byeol have turned twenty international age, and Nari has turned twenty-four in international age. Earlier this year, Sera and Rose turned twenty-two and twenty-three respectively. This morning the girls streamed their joint birthday event, and viewers were surprised to find celebrity guests such as SHINee's Jonghyun and Onew, EXO's Suho, and CN Blue's Jungshin. Jonghyun was revealed to be Rose's childhood friend, and when Rose introduced WARdEN so SHINee on the day of their debut music show performance, Onew and Sera got very close! EXO's Suho is a similar story for Byeol, the two met backstage and became close, while CN Blue's Jungshin is Sera's cousin! Apparently Baekhyun was meant to appear as well as Maeri's close friend, but was unable to due to a clash in schedules.

Besides idols, there were other guests as well! UouO Media trainees Yoon Sooyoung (Who has recently started filming CF's for A lA Me, the makeup brand WARdEN endorses) and Shim Chae Yeon (A very new trainee despite her age) came to support their sunbaes. WARdEN's "normal" friends attended as well, like Byeol's close friend Lee Hyunae, Sera's older brother Lee Sungjin, and Nari's best friend, Jung Jaehwa. They're all so beautiful, fans claim those five should make a coed group of their own!

After the celebration, each member posted an individual and one group selca to commemorate the evening. Happy birthday to all five girls!
