BloodKiss : Vampire romance

This is a story-rich visual novel played in portrait mode, where players make choices to pursue romantic relationships with vampire characters. While playable in short sessions and easily interruptible, progression is heavily gated by a gem system that requires either significant ad watching or real-money purchases to unlock desired story paths and endings. It's best suited for players who enjoy narrative-driven romance games and are patient with or willing to pay for monetization.
