I loved the male lead's personality. Lu Sicheng is quite awesome and the actor is perfect for the role.
I love that he is a rascal, the way he teases the main female lead and the way he falls inlove with her.
I also enjoyed the e-sports theme even though it's my first time watching something with this theme.
I started watching because of some short youtube clips taken from the drama, where the main lead is all lovey dovey with the female lead. I LOVE his personality.
Best male lead personality archetype ever as far as I am concerned. No love triangles. No angsty drama. Just their world and how they fall inlove. But mainly for me, Lu Sicheng (main male lead) is the reason why I started watching this drama, why I finished it and why I would rewatch it in the future.

If everything would've been the same but Lu Sicheng's personality would've been different, I wouldn't have been as interested.

Perfect mix of good looks, teasingness, playfulness and rascalness. I'm smitten with this character.
