Stop acting so scandalized that a smut manhwa with multiple pretty girls and one guy is a harem and he has sex with more than one girl you freaks. I like Sera more than Seyoung because Seyoung is fairly an ass. Sera had to be pounded into submission but at least she relents and is kind of cute about her defeat plus she's fairly flirty and amicable with the MC outside of sex meanwhile Seyoung is just an ASS to him outside of and during sex like trashing his house, bending his spoons and messing up his clothes and then during sex she never acts cute and just insults MC who reciprocates in return until one of them gets pleasured until brain dead then they stop being asses to each other. I understand people want big "buff" tall girl to get with the short king but they never feel like they like each other during or outside of sex and Sera at least acts like she's interested in him outside of sex and again her apologetically and pleasingly asking to be plowed was both sexy and cute and I can't wait for the next chapter. Also Sera is equal/close in height to him so I also think that's rare and worth noting.
Also none of that "we didn't know it was a harem earlier" you could've dropped it but your asses got sunk-cost-fallacy-ed.
