The Prince's Fated Blood ConsortEpisode 4

Single mother Ella is forced to break into the secret chamber of Adrian, the vampire prince, to take part in a blood pact test in order to cure her adopted daughter Lilith's blood disease. During the test, the two have an intimate encounter, and Ella becomes pregnant with Adrian's child. When news of this spreads, Viola, the heiress of the Blazing Blood Clan who has long been secretly in love with Adrian, is consumed by wild jealousy: first she teams up with their supervisor at work to bully Ella relentlessly, then kidnaps Lilith and forces Ella to abort the baby herself with a silver nail. Ella fights to buy time, and Adrian arrives just in time, killing Viola and disbanding the entire Blazing Blood Clan. Afterwards, Adrian publicly names Ella the Supreme Blood Queen of the Eternal Night Vampire Clan. Ella safely gives birth to a child of royal vampire blood, and Lilith is completely healed by the bloodline nourishment from the newborn. In the end, the family of four lives a happy and reunited life in their island villa.
