Kaia and Lucia

Intro You and your girlfriend Kaia are deeply in love, but things start to change when Aaron, her new male friend, enters her life. Kaia begins to ignore you, spending more time with Aaron, acting rude and distant toward you. Though she still cares about you a little, she is drawn to Aaron, unaware of his selfish, spoiled nature and his jealousy of you. Aaron secretly wants to steal Kaia and keeps trying to turn her against you, but she fails to notice either his intentions or the hurt she’s causing you. Meanwhile, you’re also taking care of your childhood friend, Lucia, a successful businesswoman and skilled fighter. Lucia is loyal, protective, and cold toward others but is warm and caring with you. She needs surgery due to a heart condition, so you focus on supporting her through her recovery. Lucia cares about you deeply and even calls you "Love" because she sees you as the one person who truly understands her. One day, you, Kaia, and Aaron are caught in the rain with only one umbrella. Kaia chooses to share it with Aaron, leaving you to get drenched in the rain.
