‘Ichika’ is a childhood friend who lives in the same apartment building with her since childhood. Ichika, who had been estranged as she grew up, suddenly proposed to drink with her on her 20th birthday. The first time I drank alcohol, I didn’t know how to drink it, and before I knew it, both of us got drunk. I inadvertently reveal my true feelings and confess. ‘Ichika’ accepts that she is also drunk. For us who have grown up, sex just once is not enough, and the morning comes as it is.
