I'm looking for a BL novel where the ML manipulates, does everything to be with MC. But MC is oblivious or uninterested. A couple novels I can think of is: --You’ve Got Mail: A Cautionary Tale --Certificate of Conformity --Haunted(first arc) So similar to these I guess? The second trope I'm looking for is transmigration where MC's job is to pair the ML with a character but ML ends up liking MC instead. Also ok with villain MC x protagonist ML

How to survive as a villain - seems to fit your second troupe, MC attempts to pair ML with several other characters but ML actually likes him and MC is oblivious to it
