Oedo Hikeshi Zue(2013)

"Wa-gumi", group of firefighters were celebrating Kensuke, newcomer to join them. All of a sudden, there went fire-bell to warn that fire had broken out. They all ran to try and stop it from spreading. Kensuke ran into the house to rescue a boy left behind in the fire, but got stuck due to the fire and smoke. Found the boy secured already, Kohaku ran in after Kensuke to save him from burning to death. They jumped into the river, and Kohaku gave him CPR to save his life. Kensuke woke up and felt a great deal of emotion for being saved and kissed Kohaku.
