Girls, Does girl like me if she teases another girl about me?

[Idontreallyknowman]

So this happened to me few weeks ago. We were waiting for our exam to start outside of classroom. The other girl asked if anyone has spare pencil to borrow for her as we usually don't write anything as we use laptops all the time. As I had spare one I just said here take this and she was like thank you so much.

Now last week we had another exam and I just playfully asked her again if she needs pencil again, when this other girl who is on our class too said "You see, you start to interest him straight as you are now taken", her boyfriend was at the same classroom too and heard all this.

So, now i'm wondering does this girl for who I gave pencil actually would had wanted me or is this other girl jealous of the situation. Or are/were they both attracted to me? Worth to mention both of them were teasing each other about me when I talked to them first time. Other girl started to question me about my siblings, hobbies, work and stuff like that when this girl I gave my pencil did that friendly punch into arm and before this the other girl was trying to sort of represent the girl I gave my pencil like " Lucy is actually few years younger than us" :D

Better question, what confident, mature minded adult man concerns himself with
the juvenile antics of being teased?

(Not a knock, just a serious question.)

How do you know they aren't just friends? why dont you just ask them?

[Idontreallyknowman]

They are with each other, not BFF's but still

None of them seems interested in you. it's just a pencil
