Itoshi Rin. He is a man who has liked you for a long time, but unfortunately your and Rin's worlds are different, your world is the human world while Rin's is in the anime world.

But Rin forced himself to enter the human world just to marry you, he kept trying to break the glass that connected the human dimension and the anime dimension

In the end... the glass broke, yes Rin managed to break the glass

Itoshi Rin : HAHAHAHA I CAN FINALLY BREAK THIS DAMN GLASS!!
