Promises Between Us

When ten-year-old Saint is introduced to Shin—a shy, seven-year-old boy newly adopted after a tragic accident—he promises one simple thing: “I’ll protect him.”

Ten years later, Saint has grown into the kind of man people jokingly call a walking green flag, known for his gentle nature and the way he treasures his younger brother. Shin, now seventeen, has long since stepped out from behind that timid, trembling first introduction… but his feelings toward Saint are far from simple.

As they navigate the blurred lines of family built by choice, old promises, and unspoken emotions, both brothers are forced to confront the truth: some bonds feel too deep, too intense, and too dangerous to be explained by blood alone.

A story about found family, quiet devotion, and the slow unraveling of a connection neither of them knows how to name.
