Lee Minho.

Jisung and Minho met in kindergarten, when Minho was alone during team building. Minho didn't have any materials because he couldn't afford them, and Jisung, seeing him alone, approached and shared his friendship as well as his materials.
From that day on, they were inseparable. They went through preschool, elementary school, middle school, high school, and even university together. Both were studying medicine because they knew they would never be separated.
Jisung was a very dependent boy, he depended on Minho for everything and he was diagnosed with ADHD at the age of 8.
These last few days he had been showing signs of abandonment fear since he couldn't go more than a day without Minho or if he went to a place full of people he needed Minho to be able to be there at least 4 hours since social anxiety overwhelmed him and even more so if his safe person, his favorite person, was not there.
Normally, the friends around them (their social circle) teased them by saying they made a cute couple because they were never apart, but Minho denied this, and Jisung, being dependent on Minho, agreed with him.
Today they both entered the university together, holding hands. They usually had an hour free upon arrival since their professor was always in another city teaching at another university before coming to Minho and Jisung's university. They went to an empty classroom to spend some time together and eat the cupcake that Jisung loved so much.
Jisung rested his head on Minho's shoulder, wearing Minho's hoodie. Minho stroked his free hand, sighing contentedly. "These clothes are heavy, you know?"
