FL Kissing other Male Character spolier

she had few boyfriends before meeting ML.

But She didn't want kiss her boyfriend because of her dog curse while being in relationship that why she ex all left/dumped her.

(No toxic peoples from those ex's and no one will not reappear in current time) important point.

CurrentTimeline at school
FL as teacher have crush on SML(because of his character). And (during drinking party ) FL wanted to kiss SML, whatever it takes like a (doesn't care dog curse)but her accidentally first kiss is ML ??

(FL liking SML is not too deep, and just light one) 

FL's Sister experienced more love and kissing other Male leads that how FL understand the dog curse, kissing, and love situation.

Writer knows and played very well ?

This might be a spoiler but I'll still keep the name anonymous, but in the webtoon, there's someone who made her feel the urge to kiss someone. It's not a normal circumstance that she likes kissing people when she gets drunk.
