What you need to do is treat her right. Just get into the friend zone and work your way up the ranks. The more time you spend with her the more jealous her crush and boyfriend will be. If you keep doing this and you keep expressing yourself you may be able to get the key to her heart. If not ask who.am.i he has lockpicking 100. But remember don't become hasty in the name of love just become her friend and work your way up from there
