You and Xiao are dating

Let's say that you both are kinda nerds but still have a great personality that one could have. You both got to know each other for 5 months before Xiao asked you out on a study date. And of course, you accepted it since you caught some feelings for him too

Later on in the Library late at night.. You both were studying together, revising the topics that you had learnt earlier at school.

You had some troubles understanding here and there but he helped you out.
