It's either Home, At Last or A Long Due Reunion depending on preference

Oh, ok, I got Home, at last. A Long Due Reunion is the only one I need out of Zen's routes. I just finished getting Peacefull times(?) and man, I kinda hate Zen's ending in that one. I can't really see him with anyone but Ash lol. I've just been pretending this whole time that after whoever Ash chooses dies her and Zen reconnect, well gotta at that one to it now too lol. I've never really had this issue before. Normally I just play all the endings as they are. So, thanks for this new feeling lol
