I think these would count: I married an exasperating eunuch. It's a novel about an MC pursuing a eunuch ML and she's quite shameless and bold about it. Bai Fumei in the 70s. MC goes back in time and pursues the ML who was her love later in her first life. ML is a prickly pear but warms up with time.
Ambiguous Relationship the fl chased the ml and then figures out that he doesn't like her back so she stops but because they are mutual friends and stuff they keep running into each other and fall in love ig I Seem Unsuited for Dating i don't remember if the fl explicitly was chasing the ml but it was a decent book so u can still give it a go
He’s Mine, No Objections Allowed Read this quite some time ago, but if I remembered correctly, the FL chases the ML
Jiaochen Slowly Falling for Changkong - it is more or less the FL's initiative, though they get together pretty fast. A Game To Make Him Fall - a JP oneshot.
