You Were Many Years Too Late

Are There Any Novels Where the Male Lead Has Had a Crush on the Female Lead for Years?

It has to be available on Tomato Novel. I'm too lazy to search through other apps. I want something entirely sweet with no angst. I'm picky about chastity, so I won't read a novel unless both leads have only ever been with each other. Please!! And stop recommending "The National Film Emperor Has a Secret Crush on Me". I've already read it.
