As a result of continuing to receive pure love from Aruba, he is gradually fascinated.

Cast information

Ayumu Murase (role of Alba)

The most recommended and brothers? ! While being surprised by the sensational title, this work has a serious setting in its actual setting.
However, Aruba’s straight and hard work contributes to the axis of the work and the warm atmosphere of the work, so I think everyone can watch it with confidence.
Please look forward to the on-air!

Orsis: Shota Aoi

This time, I will play the role of Orsis in this work!
Partly because he’s the main character, Alba-kun, I’d like to act so that I can make it look nice to everyone as well as Alba-kun.
Orsis is the first impression and as the story progresses
I’m looking forward to being able to play that change myself as a young man who seems to be able to see changes!
It will be a TV animation, and I will play it with all my heart so that the color of this work will be darker, so please look forward to it!
Thank you very much!
