well,This 질문 is refeering to as,you like the guy the same as a bestfriend 또는 at the same level as your best friend? well,I think 당신 refeered to as 당신 like the guy as a bestfriend but 당신 also feel the emotions of 사랑 towards him. My 조언 for 당신 would be to not let him go, I know feelings might change over time and there is a slight percent that 당신 won't be interested anymore. BUT I think that 당신 should first observe what 당신 really feel for him,and if he possibly likes 당신 too. If 당신 find this emotions and 당신 feel 당신 float while talking to him,and he can't get that smile out of his face,surely youshouldn't let him go. Possibly 당신 two might be the perfect match.
