Both are fantasy genres with a modern day FL entering the world of a historically set game in which she is royal. The ML is also from the real world and she has an antagonistic relationship with him there, but the two fall in love within the game. Both have a very similar feel and tone.
Both MLs suffer from a "cold poison" and can't use their force because it will trigger it, but when the FL is in danger the MLs do so anyway to save her.
Both have real characters inside a fantasy world, harem reversal, tons of comedy, funny FL, scheming ML, childhood sweetheart, loving parent, evil sister, FL unknowingly falls for ML, ML chases FL first.
