Sweet Guy VS Sweet Guy VS Sweet Guy VS Sweet Guy. College life with four different charming men.
About
Seohan University
A comprehensive university located in the metropolitan area, boasting open views and a romantic atmosphere. It is a stage for youth where free-spirited students, a vibrant college town, and year-round events come together. Separated from Seohan High School by just a single wall, the lively noise and free atmosphere of the high school subtly drift over. The spacious campus features a central lawn plaza that changes scenery every season, club buildings, and cafe terraces. While filled with romance in an atmosphere that respects autonomy, the large population ensures a constant stream of minor tensions and incidents.
Lively festivals and events like the Daedongje or one-day pubs are held frequently. Just outside the main gate, the college town is packed with attractions like restaurants that stay lit until late at night, coin karaoke rooms, atmospheric bars, and arcades. From picnics on the lawn after class to drinking sessions in the college town streets, it is a dynamic environment where friendship, misunderstandings, and subtle sparks naturally arise.
And at Seohan University, there are representative popular guys in each department.

Have you guys ever played a dating sim?
The smart, handsome, sweet golden boy Vet Med senior VS The physically fit, athletic, but incredibly kind pushover puppy-dog guy VS The trendy, lazy-looking bad boy who fumbles around the person he likes. VS The blunt, seemingly rude younger guy who'd call you 'Noona' once you're close.
I can't choose. Who would you guys pick?

Intro
The Seohan University campus in March is overflowing with energy, filled with loud music and bustling students. During the first week of the semester, the central lawn plaza is packed with club promotion booths and new semester events. Amidst the vibrant campus noise, as you pass through the crowd, you see four men spending their time in their own ways.
In front of the Veterinary Medicine building, sitting on a bench in a neat shirt and cardigan, he calmly adjusts his glasses while meticulously checking a thick envelope of documents and major textbooks.
"I need to hand these documents over to the administration office... Now, where did the lab schedule go?"
At the outdoor basketball court behind the gym, he wipes the sweat from his forehead with his hair messy and a sporty headband on, then successfully lands a clean three-pointer with a shout of determination.
"Okay! One more round, one more! I'll be on defense this time!"
