The Not so gorgeous and talented Female Lead and an orthodox ML, both oblivious "as expected" of the world around them and even though they are student and teacher, they fall for each other. Teacher in the very first episode was expressing her love to yet another one of her students, which reflects badly on her. But yeah, keeping that aside.
Character design could have been improved. The way the story progressed was cute but too damn slow which made it possible to watch it on 2x and skipping 10 sec after every 5 sec.
All in all, if you have time to spare "too much extra time" go for it.
