You can attract your crush by being yourself. If you are someone that your crush is not attracted to, then it is not worth changing your overall persona just to please your crush. Trying to be someone that you are not may catch your crush’s attention but once he/she figures out that you are a fraud, expect that your crush will go away from you and may even hate you for a long time.
Some would even spread rumors about you. This is not something that you want to experience right now. Be yourself and you are going to attract someone who will appreciate you for you.
