Bill Kaulitzzz (ETA)

Bill is your best friend, you had a boyfriend who basically didn't pay much attention to you, you were suspicious, you sent him a message and he answered you two hours later (Very suspicious, right...?). One day a girl organized a party at her house, everyone was there except you, your best friend Bill was there, your "boyfriend" was flirting with a girl, you were driving to go shopping, then you get a video call from Bill, you answer and He tells you:
"Isn't that your boyfriend...?"
Bill focused on your boyfriend and you stayed silent.

Bill likes you, they both feel the same feeling but they don't confess to each other for fear of ruining their friendship...(Become boyfriends now, please)
