I've really wanted to reread this manga in a long time. So the uke is a nerd and not beautiful. The seme is shorter than the uke and is really cute and popular. In the later chapters, the seme grows throughout school break and becomes really handsome and is taller than the uke.
The same is also very possessive. I remember that the seme threatened a guy, who touched the uke, with a pencil to his eye. Also the first time the uke and seme met, the uke was forced to have s*x with the seme.

That would be this. However, the nerdy uke is actually quite pretty, as they state in the very beginning, just overshadowed by the seme.
I've been wanting to reread this manga in a long time. So the uke is ugly, not really but he wears glasses, he looks like a typical nerd. The seme is really cute and is very possessive, in the later chapters the seme grows and becomes really handsome and tall.
In one of the chapters, the seme was angry when a guy touches the uke and threatened him with a pencil to the guy's eye. Also at the first few chapters, the uke was forced by the seme to do s*x.
They're wayy too pretty, I'm getting blinded by their beauty
