Description:

It all starts with your typical childhood friend love story—average Kanade pining after his dandy best friend, Munechika. There’s just one big problem with their high school romance—Kanade’s a Beta, and Munechika’s an Alpha! And everyone knows that Alpha/Beta pairing just isn’t compatible…on a physical level. But when Kanade goes into heat as an Omega for the first time, will Munechika be there to give him a helping hand?
