SUMMONING YAOI DETECTIVES!!

I'm looking for a yaoi where the MC works for the ML. Due to his debts, MC moves into the ML's house with a fellow colleague. *Sexual tension ensues*. Fellow colleague then moves out but MC remains with the ML. My memory's hazy on this so I can't remember what happens after.



Extra details: Both ML and MC had black hair...I think. When MC and his fellow colleague moved into the ML's house, the first warning ML gave them was not to touch anything. Somehow or the other, MC ended up giving ML a blowjob. The colleague had unshaded hair in the manga, so he was probably blonde. ML always wore a suit to work, while MC dressed casually. Ah, and ML wasn't a jerk to the MC.



I've been dying to reread this. Any help will be appreciated!
