That happens when you're a lonely femcel/incel and the opposite gender shows you some kindness, if you wanted to fuck a femcel you had to make sure you are the first one they fall in love with, because once they fall for someone else then everyone is friendzoned to oblivion, even if the one they like gets a gf they will wait on the sidelines for a chance like a lapdog.
They are easy and at the same time not.
