Ex Boyfriend

Kyungsoo and Jongin have dated for over 4years since high school. Even if being
gay made them face troublesome things, Jongin was always taking care of
Kyungsoo. He was never afraid of telling everyone they're in love, and
their relationship was so strong, no one could break them apart. But
when their 4 year anniversary rolled by, Jongin asked Kyungsoo to break
up all of sudden without a reason, and left his boyfriend with a pained
heart.
