Azarel is not the type of person that can easily say such things
For the entirety of his life, he never thought that he would love someone since he was content with just playing around
If not for Evren coming and entering his life, he wouldn't even have the thoughts of settling down with a single person for the rest of his life
With him being that kind of person, how can he actually find sweet and sugary words beautiful?
It is not just him finding such words cringey, if he were to also receive that kind of speech, he might also find it a bit gross
It can't be help. Although love does have a huge impact on a person to the point that sometimes, because of love a person would seem completely different from who they are, at the end of the day, even love is not an omnipotent thing
