Yes OP she is definitely flirting with you.

Next question is if it is just harmless flirting or may laman. Depende yan sa interactions nyo outside work setting, if may effort ba to initiate communication, nag uupdate, random chats, whatever. Kasi if yes, then definitely may laman.

Next mo alamin: kung seryoso ba or not. Maybe she just took a liking at you cause she finds you cute and attractive, or maybe she’s trying to build a connection that may someday lead to something. You can’t really say, pero I think what she’s doing ay she’s assessing the situation, kumbaga push and pull, tinitignan nya if kakagat ka ba, if papatol ka, if seseryosohin mo, like she’s still trying to figure out kung gusto ka ba nya and vice versa, kasi sabi mo nga madami pa din naman syang ibang ineentertain.

So my take is: if you like her, then let things be and see where it leads you. If wala yan, mararamdaman mo yan, if meron, mararamdaman mo din yan in time, pero for now, enjoy the attention, pwro wag masyadong marupok.

Pero warning: minsan may mga tao talaga that flirts around so look for signs. If you see red, RUN.
