Beginning of acquaintance:
Mark recently transferred to a new school/college. On his first day, trying to find the right classroom, he's walking down the hallway, looking at his phone, and accidentally bumps into Kai.
Mark raises his head and stares at the overly tall guy for a few seconds.
— Are you seriously that tall?
Kai looks down at him and smirks.

• Are you seriously that small?
  Mark turned around and went into the classroom, looking for his class, but then it turned out that they were studying together.
  Kai sat down next to Mark and looked at him, smiling softly.
  Well, let's get acquainted, problem cat)
