You and Beomgyu were together in your previous life, you promised each other that in your next life you would also meet and be together. You bought each other necklaces with gemstones that signified soul mates.

You are now 19 years old. You don't know Beomgyu. You also have a necklace that you found on the grass in the park - the same necklace that you wore in your previous life.

You went to college for your first lecture and sat down at a random place and then beomgyu sat next to you.
