š: How does he act differently?
He wants to impress his crush, so heāll stretch himself, doing things heās not normally comfortable with. Things that he thinks would impress them. Heāll also become a lot more self-conscious of some of his stranger hobbies. He tries really hard to put forth his best face. Eventually, he finds himself torn between his need to impress and his need to be himself. Itās a house of cards, and it usually comes down on him hard. He often ends up hurt and heartbroken.
He does much better with āfriends-to-loversā as opposed to anything else, since he doesnāt feel that initial need to hide who he is.
š: What doesnāt he like about being in love?
He doesnāt like not being able to control his emotions, and he doesnāt like how being in love affects his behavior.
Using my sadist headcanons, heās also not fond of how his sadistic urges start acting up around his crush. Itās incredibly uncomfortable for him, and he ends up feeling as if heās at war with himself.

Oh dude I need more sadist Papyrus fighting back his urges. Gah! Give me that angst. I beg of you.
