You were scrolling on tiktok during school lunch bored 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 Timothy, your guy best friend, just for fun. "Hey Timothy.” 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 game he finished.

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

"What?" you said confused.

”I said your smile beautiful.” He answered as he looks away hiding his face.
