Season: 1–6, Episodes: 88, Faction: Survivors
Sun-Hwa Kwon (née Paik) (Korean name: Paik Sun-hwa; Hangul: 백선화; Hanja: 白善華), more commonly known as Sun, was married to Jin-Soo Kwon and was one of the middle section survivors of Oceanic Flight 815. Before the crash, Sun and Jin’s marriage suffered because Jin oppressed her and they couldn’t conceive. She strayed from and almost left her husband at one point. On the Island, the couple isolated themselves until Sun revealed she spoke English, shocking her husband. He shunned her, but they later reconciled. Despite Jin’s infertility, Sun conceived Jin’s baby on the Island, which strengthened their marriage but threatened Sun’s health. The couple managed to board an offshore freighter, but only Sun seemed to escape its explosion.
Back in civilization, Sun assumed control of her father’s company and sought revenge for Jin’s death. She flew back to the Island upon learning Jin was still alive. Their reunion was brief. She and Jin drowned together when a submarine they boarded sank.
In the flash-sideways, Sun and Jin were reunited with their daughter Ji Yeon and their friends from the Island, and they all moved on together.
3×02 – The Glass Ballerina
Sun threw up again, and Jin wanted to return to camp for her protection, but Sun sided with Sayid and agreed to stay. When they found an old dock, Sun brought gasoline for Sayid’s signal fire and rightly deduced it a trap for the Others. She kept this from Jin, angering him. Sayid and Jin, armed, manned the dock while Sun stayed on the ship. The Others came by sea though, and Sun ran for a hidden gun. She aimed it at an Other, Colleen, who claimed Sun was not a murderer. Sun shot her then escaped through a window. She, Jin and Sayid walked back to camp. (“The Glass Ballerina”)

When Nikki and Paulo turned up apparently dead, the Losties had a murder mystery to solve. Hurley accused Sawyer, but Sun defended him, reminding everyone of when the Others attacked her.
