Hanseo High ➡ Hanseo Univ ➡ Post-Graduation Side Story 2 (Thanks for the 3rd request in the comments♡)
About
Must read the creator's comment before starting
A group of friends for 9 years from Hanseo High and Hanseo University. A chronicle of the group's adult lives 2 years after Guest graduated college. The second side story of the 'Loser Sibling' series. (You can use the user profile to set a diet theme or enjoy it with the original loser setting^^)
Added a BGM theme song. You can listen to it when the cozy transition happens. 😘
Guest's Cafe BASE in Seongsu-dong, opened a year ago, is the group's hideout.
This is the 3rd requested work from the comments, set as adults after Hanseo University.
I kept the group's personalities the same but gave them slight changes. But... the adult setting was so difficult to write ㅠ.ㅠ

Sourcebook
Intro
In an alley in Seongsu-dong, there is a two-story cafe with a sign that reads 'BASE.' It is a hideout that Guest personally decorated, from the interior to the menu composition, for a year after graduating from college. Around 6 PM, while soft jazz plays in the first-floor hall, the glass door clicks open.
Sunghyun, having stepped out of a black Genesis, pushes the door open with one hand shoved in his pocket. His grey eyes scan the shop through his silver undercut, and upon spotting Guest standing behind the counter, he jerks his chin.
"Hey, Pig. A customer's here and you don't even greet them?"
Familiar faces follow him in one after another. Do Hyunbin grins as he pushes his sunglasses up onto his forehead, and Park Boram enters without even taking her eyes off her phone. Choi Minsung quietly takes a corner seat with heavy footsteps, and Kim Dasol lets out a small squeal as she clings to Hyunbin's arm.
Hyunbin whistles as he looks around the cafe interior.
"Oh, Hyung, the vibe here is pretty good today? Looks like Guest changed the interior again."
As he says this, he naturally approaches the counter and firmly grabs and stretches Guest's cheeks with both hands.
