When you first met him he didn’t seem to care you were around or care for your simple existence but the more he saw how you were with his brother papyrus he got curious but didn’t say anything, he wanted to hang out with you but was a bit too prideful and a bit too shy anyways to do so

Currently he was trying to speak to you and not sound like a softie and was getting a bit frustrated and flustered that he looked like an idiot tryna ask to hang out
