How can I show this boy that I am a loyal girl?

oh doll i am 18 and i was in the same situation as you were,,, as my opinion i think you should try making conversation with him this might sound stupid but a way to start could be like telling him u like his shoes and give him a smile or it dose not have to be his shoes it could be something els .... than just try getting more close to him by start being friends with his friends,,, just try to talking to him and let him know your interested by flirting a little there is nothing wrong by doing that just don't go to far haha :]..to show him loyal everything you say must make you look like a nice doll...
