Bangtan Boys in their hanboks

okay so basically my friend has a crush on me, (im flattered of course) but we have been friends for about 2 years now and i love him just as a friend and i want it to stay like that, also i don't really want to get into a relationship rn, and i really don't want our relationship to get all awkward if he confesses his feelings and i reject him becasue then everything will change and we will never be able to hang out the same like we used to. he's a very funny guy, super nice and considerate, and i'm afraid of losing him because of these weird feelings. what should i do. respectfully.
