This is amazing. The eccentric-genius and insecure damsel trope, and yet, also not.
The guy speaks his mind and does what he wants, sure, but he is also thoughtful and considerate and caring, not to mention hella passionate.
The girl is modest and reserved and was a complete virgin until not too long ago, yes, but she can also speak her mind and stand her ground and accept love and give it back. Her self-reflections are not self-harm, and she knows when to bounce her thoughts (both negative and positive) off others and not keep them bottled up like a shoujo main character.
Because this is how adults should be.
