Works on the same principle with "Almost Heart-Warming" pool
Moments where it's almost heart breaking, almost/already depressing, almost "Soul Crushingly Depressing" worthy, but something just changes it, like an intervention from someone, something humorous/disgustingly adorable happening, or the characters contradicting themselves or doing/saying something to brighten the mood.
Other forms of this include, 1. The intention was harmful, very malicious, thoughtless, hateful, etc., but it didn't turn out as expected. 2. The opposite, when what a character does seems neglectful or hateful, but their intentions are noble. 3. The attempted drama is ruined un/intentionally by NARM or WANGST
