Sadly there's no side stories but there's the author's note on the official site Lezhin. Stated that Skyler and Yeonduk is living together and one time Yeonduk got drunk because his subaes told him to drink. In the end, Skyler worried a lot for Yeonduk. Nothing about Leo or Stella though and there are no other stories from the author. So this is the only one.
Oh thank you for that
Does anyone here know the creator's twitter account? Is there a side story? Or anything that portrays the youngest sibling, Leo? Because all the time I was reading this, my mind would constantly wander on Leo, I mean, I just feel sorry for him because even if he's the favorite child of the mom, he still has his own struggles, and being the favorite child of their mom is such a big burden to carry, knowing their mom's and family's condition. I just really feel sorry for the kid
