Gay or not?

Meliodas is a normal boy. He is a bit of a bad boy together with his group, the seven deadly sins. He never had an interest in anyone before, but when a new student starts in his class, he can't just not like him. In a romantic way.

How will he be able to tell everyone he is gay? How will everyone react? How will the new student react when he gets to know Meliodas loves him?

Then the most important question. Is he really gay?
