A Story of Love That I Do Not Know

Arima loves Saeki, his wholesome and earnest lover with an enticing pheromone, but Saeki's ex is Arima's neighbor Tanaka. Saeki convinced Arima to dump Tanaka and date him instead. Meanwhile, Saeki still bears scars from the BDSM activities his ex-lover forced on him, and he feels uneasy every time Arima's is tender toward him... The title story and a newly drawn comic describing the love life of the sadistic aggressive Tanaka are included, as well as a short BL story that is a bit sad!
