Zeng was putting Yul's clothes away for the laundry while the said man laid sprawled on the bed after he got changed. He had had a little too much for dinner outside that night and he was drunk. However, it wasn't their celebration at home that got him drunk.
His seniors at work had arranged a small farewell for him as soon he would be transferring from their smaller police station to another one which had the narcotics department. Under peer pressure, he had to drink a little as his colleagues had worded and Zeng wasn't too happy when he received a call from a drunk Yul to tell him how he loved him in an incoherent speech. His mumbled words asked his boyfriend to pick him up as he couldn't drive.
The doctor somehow got the location of the bar and got there with his car. When he arrived, he had the plain, long-sleeved shirt on, meaning he had come there directly from work.
