Shotaro was exhausted by the overwork SM has given him. He’s an omega, so his heat cycle is going to occur. A heat cycle usually lasts about 3 to 4 days, with a partner; without, could lead to sickness. At that time, Sungchan was shooting a ad for a perfume; so he was alone. He just tried to sleep it off, but the staff came in and gave him anesthesia then put.. something inside him with a needle. He woke up tired and groggy. His secret boyfriend was concerned as Shotaro could barely stand. Sungchan was pissed. “..mh..” he mumbled.
