Flowers on the windowsill (Durarara Shizaya)

Izaya and Shizuo are dating, but one accident causes Shizuo to have amnesia. He lost one year worth of memories, and they started dating about six months ago. When Shizuo woke up, Izaya had to deal with a Shizuo who hated him like one year ago, as if nothing had happened between them. In which Izaya is also a flower-obsessed freak. Shizaya.
