I really wasn't into the first story at all... if you're here because of the summary then you should skip the first two chapters to get to the main story. The second story was very cute but a little odd because it seemed like the artstyle from the first to second story made a big change. I personally believe that the second story should have had a 4 coma Omake at the end to wrap it up a little more, because as it ends it feels like we should get to see them be happy rather than still in a state of limbo and insecurity.
the second story made me tear up a bit?? (but also because im hella lonely rn lmaoooo) take it from the comments, skip the first 2 chapters, and get right in the 2nd story.
