All That We Loved

Gifted basketball player, Koh You, and brainy student, Go Jun-hee, are famous for their bromance in high school. Both of them were raised by Jun-hee's grandmother and have completely opposite personalities, habits, tastes, and ideal types. They have never had a chance to conflict, but one day a beautiful transfer student named Han So-yeon shows up.

Jun-hee is rushed to the emergency room in critical condition. He is diagnosed with chronic renal failure, the same disease that his deceased brother had. Koh You is overwhelmed with grief and makes a life-time decision.

Koh You and Jun-hee return to school in better condition. They are once again captivated by So-yeon and her smile. The upcoming party brings anticipation, and it remains uncertain who will accompany So-yeon to the event.

After discovering So-yeon's secret, Koh You is in shock and contemplates whether to give up his feelings for her. Meanwhile, Jun-hee continues to worry about So-yeon, who is left alone, and secretly follows her as she cries.
