Lonely Rock for the Blind

Nekoyashiki Haru, male, 17, dropped out of school to play in a band, is blind, drinks a little but never smokes, likes to draw, although he's not very good at it...
When he returned to Shimokitazawa after many years, he had completely lost his eyesight.
Fortunately, I met a magical pink soft-bodied creature who led the way and saved me from dying in front of the dangerous stairs.
From then on, my life as a staff member in a livehouse called "Stars" began.
...
……
.........
When I sleep...I always feel like someone is saying something strange in my ear.
Yellow: You don’t have to try anymore, kitten, I will always be by your side.
Blue: Let’s be friends forever. I can’t live without you.
Red: I will snatch it from the senior, please wait a moment.
Pink: Thank you... Thank you for looking at me, I will repay you with my whole life... But if you don't accept me, I will go to $^^•$+" (unintelligible voice)
[What will be my ending...?]
Cat Yashiki Haru couldn't help but think after realizing that he seemed to be more than one cat in his house.
