Suki no Onshoku wa Kikanaide

"I just might suffocate from this love that keeps growing stronger...?!"

Yuki is a music college student who has unrequited feelings for Takeshi, a genius pianist who is 10 years older than him. He has been smitten with the sound of the music Takeshi plays ever since they first met, but ever since realising his own feelings, he has always kept them hidden. However, one day, he starts living with Takeshi at his house in Vienna all because of a passing comment! After hearing Takeshi say that he could never turn down anything Yuki asks of him and being spurred on by his drunkenness, Yuki presses Takeshi to kiss him...?!
