Deep in everyone's heart, there are some people or things hidden, accompanied by joy and sorrow.
In their hearts, family members may be the sharpest sword in the world, piercing straight into their hearts and causing pain until death.
The three of them are childhood sweethearts, and the two of them are just like each other, because they feel the same way, because they cherish each other, because children who have been hurt can only lick each other's wounds, keep each other warm, and rely on each other.
There were revenges, conspiracies, and joys and sorrows along the way, but they were lucky enough to meet and work together to heal the scars in their hearts with love, friendship, and family affection.
Love is supposed to be happiness, so we show our happiness to others.
