Yes indeed - it is quite an obvious way of
checking if she has feelings for him and of course, it may seemed
to be a childish attempt - in fact many people do it all
time.
Let me teach you a counter method - play along his game. He doesn't
want to malu? Then show interest, but remain where she is. He wanna
play game of bf/gf - then play along. He wanna declare love, she
will playfully do it as well. In the end, he will be wondering
what's next.
If he likes - he would come clean eventually. Remain where she is,
until he is brave enough to avoid the jokes and be serious. Stall
the feelings, first.
Cheers
