I'll Tell You Until You Believe Me

Stephen is quite popular with inter-dimensional beings, what with his status as sorcerer supreme, good looks and compassion. Everyone wants a piece of him. Stephen is oblivious to it all, chalking it up as just weird alien customs. One day, an inter-dimensional being aids Stephen and Tony in battle, flirting with Stephen the whole time. Tony feels protective of Stephen but lets it go for now (pre-relationship, Tony’s kinda jealous yes). Only this keeps happening and it builds up, Tony can’t take anymore and confronts Stephen about why he never shoots down nor reciprocates the advances of the inter-dimensional beings. Light angst where Stephen accidentally reveals that his obliviousness stems from his insecurities. He thinks Tony is pulling his leg. “Why would anyone want someone as broken as me? Surely you jest Stark!” This somehow evolves into Tony confessing his love for Stephen.--> Prompt from (https://ironstrangeprompts.tumblr.com/post/645423104907214848/prompt-995-stephen-is-quite-popular-with#notes)
