Fics like Ketchup or Mustard?

Sans has had a crush on Frisk for a while now. Well, maybe "crush" is the wrong word. And "a while" is an understatement. But he can't bring himself to tell her about the SOUL resonance that occurred between them years ago, back when they were both too young. Hasn't it been too long? Hasn't she gotten over him? However, he might regret his inaction when he accidentally summons an alternate version of himself who has no such bones about wooing his SOULmate.
