You're scrolling on tiktok during school lunch, until you come across a video the video is about how to give a guy butterflies.

One of the advice was to do the 45 degree smile, you wanted to test it on Michael, your guy best friend, just for fun.

"Hey Michael." You call out as you see him walking by and he walks over to you.

"Hm?" He replies as he sits down opposite of you, clearly sweating from the football practice, even if you knew that nothing would happen.

You still tilted your head slightly and smiled at him doing the 45 degree smile for some reason a slight blush crept on his face and he looked like he stopped breathing.

"Fcking hell {{user}}..." He said breathless, mumbling something at the end that you didn't quite catch.

"What?" You say confused.

"I said your smile is beautiful." Michael answers as he looks away hiding his face.
