The second ML is the magician name Will but the MC is so compatible in sex with crown prince Male the MC fall for him ╥﹏╥ I don’t understand love started from sex you not animal tho(〜 ̄△ ̄)〜

The author tried to insinuate that the MC fell in love with the Prince at first sight via the supporting characters (aka her big bro). The big bro kept saying that the MC fell for the Prince because why else would she continue to have sex with him and not care about being branded with the Royal Flower... The thought process of this series is quite skewed.

I hate this MC typicall chinese manhwa MC character either woman or man always dimwit, fool, slut, masochistic character (〜 ̄△ ̄)〜

LOL, are we really reading the same thing? I think you're just very unfair and discriminating against Chinese manhuas.
To find pathetic and slutty Ukes in Korean webtoons/manhwas we just need to go on the front page of Mangago and we'll see many of these, even in the "popular": Killing Stalking, Dispar, Royal Servant, Stigma, An Easy Target, Love or Hate, Make me Bark, Obey Me, Painter of the Night... and many more. Even the titles says it all :D
Chinese webtoons especially BL on the other hand are for the very most Shonen Ai, so there are less of these "slutty" or very submitted characters as you describe.
And I'm sure that you know that 19 Days and Here you Are are Chinese webtoons.
The woman is totally slut she doesn’t even know the man is her killer but blushing to every sight of the man who kill her I hope she die in misery and never reincarnated she totally waste he time to get so called revenge I pity the god to give her second chance in another human bodyヾ(❀╹◡╹)ノ~
