When it comes to love, time is sometimes the executioner, killing away the passion and making the relationship dull; sometimes it is a good medicine, allowing people to grow and learn to cherish it, thus giving a new life to a relationship that has no hope.
The protagonist in the story spent three years completing the baptism of a relationship.
Three years ago, they shared an unforgettable love, but their relationship came to an end due to their own clumsiness and miscalculation; three years later, they reunited with their unchanging feelings for each other. Although they were hesitant to move forward because of the past hurts, they also saw each other's growth through spiritual collisions time and time again.
Their greatest luck was probably that they found each other again before it was too late.
This is probably a story of reunion, although I would rather call it a story about love and growth.
