Teeth

a girl gets transported into a fantasy ancient china world where women are significantly lower in population and treated as delicate nobles. MC encounters a group of male martial artists (?) in danger and she seems to have super strength and she helps them fight off a big tiger (?). The group finds this weird because normally the nobles would not risk themselves nor be immensely powerful or nice like MC.

any help would be appreciated, i've been looking for a while now :(

I can't recall clearly since it's been a while but the general plot is there's this host who started hating scents after being exposed to strong artificial perfumes and other smells from his clients. he comes home from work and meets this frumpy guy as his next door neighbor. he was either a professor or a researcher?

At some point during their interactions the host offhandedly comments that his neighbor's cologne smells good and the neighbor brushes it off.

a couple of stuff happen (there was an incident where the neighbor left his gas stove open and nearly died & the host saved him?) and at the end after they're together the neighbor cheekily says he already knew the host is attracted to him because he never actually wore any cologne, but any guy who likes him always mentioned how much they like his scent.

Thanks for any help!
