What is the name of this drama?

The boy is a celebrity/pop star. The girl does voice acting and has a fear of crowds. I think they both travel to Japan. She becomes his temporary assistant and he promises her tickets to her favorite band concert. He is in an accident and ends up in a coma, but his "ghost" visits the girl. They have some kind of connection through her Tamagotchi  toy.

Thank you!!

Try    Sm:)e  the girl is a voice actress but can't perform in front of people.......or there is

 Dear Prince  that involves concert tickets.  :o)
