To Heart is a Japanese adult visual novel developed by Leaf and released for the PC in 1997. It was later ported to the PlayStation and given voice acting. A second PC version, To Heart PSE was released to the PC and PlayStation with the adult scenes removed.It was followed by a sequel, To Heart 2, and two anime series.The gameplay in To Heart requires little player interaction, following predetermined scenarios with courses of interaction, focusing on the appeal of the eight female main characters. Every so often the player will come to a "decision point", and the story progresses according to the player's decisions. There are eight main plotlines, one for each of the main heroines. In order to see all the possible storylines, the player must replay the game multiple times, making different selections at the decision points.
This game contains examples of:
All Just a Dream: The first omake, where Hiroyuki wakes up in a world where his friends have swapped roles: Shiho and Akari, Lemmy and Kotone, Hoshina and Aoi, Multi and Serika.
Angst: Akari falls into this in Remember my Memories.
Art Shift: The original 1999 TV series and Remember my Memories (2004) feature drastically different character designs, color schemes, and general "looks." While this led to cries of They Changed It, Now It Sucks, RMM's style is actually closer to the original game artwork.
Hot Springs Episode: Episode 9 of Remember my Memories, but done more for drama rather than Fanservice (we do see a nude Akari) the whole scene is spent with her and Hiroyuki in a heart-to-heart talk, which in the end doesn't resolve their relationship problems.
Like Brother and Sister: Used in the original game, with the Official Couple. When Hiroyuki finally gets Akari into his bed, he is mortified to discover he can't get it up, as he thinks of her more as a little sister than actual mating material (a "decision point" appears here, giving the player the option to get over it).
It expands into a Love Dodecahedron in Remember my Memories with Kotone and Lemmy confessing to Hiroyuki, while Multi inadvertedly keeps Hiroyuki's attention enough to make Akari jealous, and then there's Masashi confessing to Akari.
My Kung-Fu Is Stronger Than Yours: The rift that developed between Aoi Matsubara and Sakashita-senpai in To Heart was the result of the latter's unacceptance of "Extreme Fighting" as a martial art. Said rift disappeared in Remember My Memories when Aoi defeated her senior Ayaka Kurusugawa who had defeated Sakashita earlier on in the tourney with one roundhouse kick to the head.
Spell My Name with an "S": The fansubs for To Heart spelled it as Remmy, but then the fansubs for Remember my Memories spelled it as Lemmy, which was the spelling official dub and sub translations used for the original To Heart anime.
Unlucky Childhood Friend: Lemmy, as revealed in Remember my Memories, was actually a childhood friend of Hiroyuki (complete with a picture of her and Hiroyuki, with her hair dyed black), but moved to America all of a sudden before the first series before coming back; she was in love with him this whole time, and she not only confessed to him in RMM, but tried to get him to elope with her when it turns out she's moving back to America soon. He turned her down though.
