This got me interested
(best ED 2019... and the OP is dope too.)
And the show is hilarious.
It's a typical rom-com but with a twist.
Although the main characters like each other, they are too proud to confess their love. They believe whoever does so first would "lose" and would end up being the "sub". The story basically follows their schemes to make the other one confess first.
Even though the setting is different and all, the humor itself reminds me of School Rumble. Over the top, silly, and full of misunderstandings.
