Help! I'm finding a yaoi manga.

Ah okay. So the seme and uke are coworkers. The seme is known for his happy and cool personality while the uke is the strict boss. Uhm. But in reality, the seme is actually a sadist and then there's this chapter where the seme left the uke blindfolded and cuffed? He left the seme to buy something from convenience store. The uke wear glasses by the way. Oh my gash. That's all i remember.
