I really like these sorts of scenes with Undertale characters (as well as any others, but Undertale seems especially fitting). It is my honest opinion that slice-of-life, as a genre, is severely underestimated. You don't need high drama, explosive action, and tragic/angsty plotlines just to create something that'll be fun to read.
