Mrs Liu needed to undergo a bone marrow transplant immediately. Guobin's school initiated a campaign, appealing to all students and parents to go for a blood test to find a compatible bone marrow.

Terry brought his family for the blood test. It was later found out that Mr Khoo's bone marrow was compatible for a transplant. In a twist of fate, on the actual day of transplant, the doctors realized that they made a mistake. It was Mrs Khoo's bone marrow which was compatible!
