Um, I don't know if there is any yaoi with a plot like this. I want to read a BL manga where the couple is not know from the beginning. In fact they may know each other, work together anything but have no feelings or attraction toward each other. They may even have other partners but later break up or so. I just need this unexpected love, they may know each other but not have anything in common. Maybe due to a project they have to do together, then some interaction may happen between them. One of the, may even appear much later, in second-third volume of the story?

One eg. could be a teacher who was spying on another teacher because the latter one was after the students and so on. And in the end they fall in love out of nowhere It's just a random example

I know this explanation is quite clumsy but I just want to be TOTALLY surprised with the couple. This has to be a BIG SHOCK with of course a later development of the couple

I found Tsuki to Sandal quite interesting(the student couple), it could be sth like this
Please not a sweet-innocent-weak uke. Thanks!

Kage Aru Tokoro ni - OK, it's not really a surprise because, hey, there are only two characters and it's yaoi, but it's unexpected from the characters' point of view.
