Iyashite Otosu summary:

The way this big, tall, younger guy pampers me is dangerously addictive! After working overtime one day, corporate slave Sugiura Rio misses the last train and finds himself stumbling into Sui, the handsome employee from the convenience store he frequents. Sui is concerned about Rio,who seems to be feeling unwell, but the moment their hands touch, Rio suddenly blacks out. When he comes to, he finds a naked Sui right in front of him and can’t seem to remember how he got there! A heartwarming love story where an overworked, easily-swayed salaryman finds relief in the irresistibly warm, healing embrace of a high-spec convenience store employee.
