For a moment Frisk freezes, not quite believing what they just heard. Does he really...even after everything? With what Sans knows, what he's seen, what they somehow still let happen...

With a soft, strangled sob Frisk buries themself against Sans's shoulder even further, but this time it's nothing but pure relief. Even if things aren't the same, it's still going to be okay. They don't have to listen to that tiny knot of fear in the back of their mind anymore. They try to say something, but it's broken up so much to be barely understood; still, the word 'love' was definitely in there somewhere.
