The Valentine's Day After Endings were added in Update 1.6.7 for both Android and iOS. The DLC consists of one extra After Ending for each character, excluding V and Ray, new ringtones (texts, calls, email), Valentines day freetalk and 16 new Album images. Each After Ending costs 50 HG each and can be bought even if you haven't bought that character's After Ending. Once bought the player will be able to access it forever.
