Well, to be fair, there's no actual evidence that there'll be any romance between Kris and Ralsei, unless you count Ralsei blushing when you position Kris next to them, Ralsei always singling Kris out for preferential treatment, Kris kissing the Ralsei mannequin, the entire Acid Tunnel of Love, the "pushing buddies" Segment on Board 1 of Tenna's game, Susie teasing Ralsei while she's pretending to be Kris on board 2, Kris proclaiming "Ralsei or Bust" when asked who they're taking to the festival, Kris playing the Acid Tunnel theme on the Holiday's piano with such emotion (seriously listen to it it's so raw), Ralsei holding an apple in front of Kris's mouth while they eat it, Kris telling Ralsei to "please be yourself" and "it's okay not to smile" before embracing them, Ralsei dressing up and telling Kris that they'll be their princess if they want after the climbing minigame, Blue outright saying that Ralsei follows in the footsteps of love, Ralsei accepting and trusting Kris even though they know they've already opened at least two dark fountains and has some plan they're not telling about, Ralsei blushing even harder than they normally do while telling Kris that their happy ending "is with you" while they're both in a hot spring, Ralsei picking the drink voucher that has Kris's dark world colours on it (also big trans hint too!) and that's before you even get to the potential horned headband connections, the possibility that Ralsei was once an integral part of Kris's very psyche that was ruptured and sundered from them at some point, and now that they're reunited as their own people years later they're both coming to truly respect and appreciate one another in ways they never could before...
