Takane no Hana wa Chirasaretai

Yukishita Hana, the kind Alpha working at Starnyaks Coffee. Renjaku, the arrogant Alpha who is a regular at said cafe, whose flower studio is located nearby. At least that's what the clients perceive, but Yukishita is actually an Omega with a crush on Renjaku. He couldn't hide his gender anymore when his first heat came unexpectedly… at age 26!
