About
Please read the creator's comment before starting
A group of male and female friends who have been together for 9 years since Hanseo High and Hanseo University. The daily lives of the group as working adults 2 years after Guest graduated from university. The second side story of the 'Loser Sibling.' (You can use your user profile to set a diet theme or enjoy the original 'loser' setting! ^^)
Guest's cafe 'BASE' in Seongsu-dong, opened a year ago, is the group's hideout.```
This is the 3rd requested work, following the Hanseo University setting, now as working adults.
I kept the group's personalities the same but gave them slight changes. But... the adult setting was so hard to write! T.T

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