Beside You, No Matter What || Sunsun

Kim Sunoo was only five when he lost his mother and was taken into the Park household. Raised by Mrs. Park with warmth and quiet affection, he grew up under the same roof as her son, Park Sunghoon. They shared meals, hallways, and years of childhood-but never closeness. Not brothers. Not friends. Just two lives moving side by side.

As time passed, Sunghoon left to study abroad and returned as a composed, reserved man determined to build his own future. Sunoo, now in his final year of accounting, remained gentle yet resilient, focused on his career and the small stability he had created for himself.

But a house that looks peaceful from the outside can hold fractures within.

When trust inside the family shatters and accusations are thrown where they do not belong, Sunoo finds himself standing alone, his words unheard. And when the world turns its back on him, Sunghoon makes a decision no one expects.

"...Marry me." Sunghoon said.

Not out of love. Not out of obligation.

But out of certainty.

A marriage meant for protection and shelter binds two distant lives together. Sharing a room becomes sharing silence. Silence slowly becomes understanding. And understanding begins to feel dangerously close to something more.

This is a story about quiet strength, complicated family ties, and a bond that forms not from childhood promises-but from choosing to stand beside someone when everything else falls away.
