YES DEFINITELY A MASTERPIECE!! THIS IS THE SIDE STORY OF SAKAKI FROM SIGNAL!!!
THE OPENLY GAY X STRAIGHT UKE
This was the realistic story that I ever read. The way sakaki approach Okada for first time. He is falling hard to him. After the struggle they're become couple. Sakaki is very practical and pessimistic person who seriously thinks before taking any step further on the other hand Okada isn't like him. He does what's in front of him and live in the present moment that's good in a way but you should always do things keeping future in your mind.
