Stardew Valley offers a few different candidates for marriage, but many players prefer to move in with Krobus instead. This roommate relationship offers many of the same perks as marriage, but one missing element is the event that takes place on the Summit after achieving "perfection" in the game. If you're married, you find your spouse at the summit and share a retrospective on your relationship. But if you live with Krobus, you'll find either Lewis or Morris at the summit, just like you would if you didn't live with anyone at all. So Krobus is what, chopped liver? 

This mod changes that. Now, when you achieve perfection while Krobus is your roommate, you'll find him waiting for you at the summit with some heartwarming things to say (or silently imply) about your relationship. (This will only work if you haven't triggered the event already in that save file.). His dialogue is written to be ambiguous about the exact nature of your relationship, so you can interpret it either platonically or romantically depending on what you prefer. 

The mod is lore-friendly and includes different versions of the event depending on whether or not the sun is still up, and whether or not it's a Friday. It also removes the sprite of Krobus being carried by a raven near the end of the event, so that he's not in two places at once. The Friday versions of the event refer to Krobus by a pronoun, which defaults to "he" (since that's what is used in the base game), but can also be changed to "they" or "she" by editing the config.json file. 

The mod is currently only in English, but if anyone wants to contribute a translation, I'd be happy to add it in an update with full credit to you. 

Some aspects of the summit event are hardcoded; for example, if Lewis is supposed to be there, I can't just tell the game "put Krobus there instead" like I could with most events. As a workaround, the mod replaces Lewis or Morris's sprites, portraits, display name and dialogue with Krobus's during the summit event, which ultimately has the same effect as replacing those characters with Krobus (although this may cause conflicts with mods that affect Lewis, Morris, or Krobus's portraits/sprites). These changes should be restricted to the summit event only and not interfere with the rest of the game, with the exception that in the credits sequence Lewis will blink between his and Krobus's sprites if you took the community center route, and that after the event Lewis's name will be "Krobus" in the social menu whenever you are in the summit area; but if you want to be safe, you can delete the mod after viewing the event since it's already served its purpose. I unfortunately couldn't customize the characters' movements, so those are the same as in the original scene (no hug, sadly), but I think it works with the dialogue I wrote.
