One of the fics got deleted, so deleted the bookmark. If you want to avoid unhappy endings or just unhappy stories I’d say don’t read: Shoeless Joe or tell me i’m your national anthem. Definitely don’t read “lilies with full hands” umm… some of the other ones are sad but I don’t think they have unhappy endings? They may have some serious content though.
Honestly if you want a happy fic I’d highly recommend “Infinite Coffee and Protection Detail”, “miles to go before I sleep”, “mistakes on the part of nature” and maybe “man on the bridge” though it’s an action story.
