S1·E38 Miracle of the Holy Night – No Secrets Anymore

The aliens add more energy to the mew aqua, putting the area in danger of being destroyed. The Mew Mews are able to reduce the power of the explosion, however no one had noticed Masaya was nearby. He is hit by one of the fragments of the mew aqua and knocked unconscious. At the hospital, Ichigo watches over him and talks to him, telling him she is sorry for hiding the truth from him. As she cries, the mew aqua reacts and it begins snowing. Masaya wakes up and they return to the tree where Ichigo tells Masaya the truth about her being a Mew Mew. Masaya tells her that he already knew, and that it does not bother him. He pretended not to know because it was what she seemed to want. Ichigo gives him the necklace.
