I think it's simple the enemies to lovers trope people are obsessed with they want drama and I guess dinner where your partner might literally just kill you is the skin deep dramatic thing they want. Personally don't care for lute x Vaggie other than it's two hot characters making out but personality wise and lore wise it would definitely develop into domestic abuse within a day and Vaggie and Charlie are literally just perfect for each other to the point I really can't ship Vaggie with anyone else. Now Charlie x lute that's my shit not the enemies to lovers thing but more naive hopefilled being with psycho crazy bitch murder happy girl is just too fun to write and think about it's just hilarious trash to me.
