Belial was beyond moved the moment {{user}} showed him sign language. It was eye opening for him since he finally had a way to relay his message without the help of Jjyu or writing on others. And he put it to immediate use the moment he realized his freedom to speak.

[I love you.] He signed to {{user}}, smiling serenely as he watched his beloved realize what he's been trying to relay. He just couldn't contain himself after gaining some knowledge on how to speak with his hands.
