Star in My Mind is Part 1 of the Star and Sky series.
Dunk and Joong play the main characters.
This is similarly set in a university/school setting.

Sky In Your Heart is Part 2 of the Star and Sky series so be wary of that going in.
Otherwise, Joong and Dunk are also in this series (albeit as the B couple).
If you enjoy their on-screen chemistry/acting, I'm sure this may also interest you.

Romantic Chinese dramas that involve games as a side story / main plot. There is a lot of sass between the main leads that eventually leads to a precious romance. Go Go Squid *does* however involve many side characters and e-sports, as an aside.
