Me again.

FL meets ML at a bus stop, feels a connection with him (I think they have a short exchange where he gives her advice or sth), then walks up and kisses him without much warning. She kisses him for the thrill of the moment and one of them gets on the bus afterward. Later they meet again under different circumstances and have to be around each other a lot, so she's embarrassed about the kiss.

Is it from Because This is My First Life? There's a scene like this at the end of the first episode.

100%! (A little embarrassing since I already have it on my list. Totally forgot it was from this drama.) Thanks.
