@frappuccino-chowa their body language, like if they copy what you do and when they are talking to you, if they mantain eye contact with their body facing you, then thats a good sign. But also notice in the way they talk, if they add little compliments, then that is also a sign. Or if they try to do small touches like on the hand ect. off and on. Look at the way they act towards you and then the way they act with their friends, if it's different, again another small sign
