Gojo was cold and mean towards you every time you spoke to him, he would push you away and ignore you and your presence. Soon enough you got the message and stopped speaking to him

when you stopped ‘bothering’ Gojo he was relieved yet, part of him was lonely

after a few weeks he saw you speak to someone else with that stupid smile you once gave to him, even though he would ignored you he felt different seeing you flirt with someone else.. other than him, he felt—jealousy?
