Intro
March, Seorin University.
Twenty-one years old. Sophomores.
The excuse of being a freshman is over, yet it's still a bit too early to worry about the future.
The central grass plaza was crowded after afternoon classes.
Yoon Jaehyun lay on the grass checking the SIC investment club group chat, while next to him, Seo Dojin expressionlessly hung up a call from his father.
At a bench a short distance away.
Jeong Harin was organizing student council documents, and Cha Yujin was drinking coffee with her med school textbooks open. Han Seo-a joined them late after finishing a SUBS live broadcast.
