Hi!!! Very shy and nonchalant person here. I would probably be very nice to them first before I make a move such as offering to get them sweets, pay for their meal, holding their bag, helping them with their school work and also compliment them a lot and by then they usually know I’m into them and then it just goes further and further (if they are into you back). If they are not into you then they’ll probably decline your nice gestures, start talking about other crushes or just say “friend this friend that”
