Dion has some weird obsessive sister complex when it comes to Roxanne. He wants to see her reactions/ expressions other than aloofness or coldness so he pushes her buttons.
Roxanne knows this + since she want the ML to escape -> she makes an alliance w/ Dion so he won’t do anything to ML.
Roxanne feeds into Dion’s desire/obsession by calling his name softly(?) (before saying “how dull”). Since we are only reading the webtoon/manwha, we don’t know if they go any further than that.











God if MC gets tricked again I’m gonna scream lmao
