A Galaxy Next Door and The ComiQ are relatively newer works from manga-ka with popular past works—the former being from the creator of Sweetness and Lightning and the latter from the creator of Yu-Gi-Oh (r.i.p. btw). One series is a light-hearted SoL romance and the other is actually a murder mystery, but I couldn't help but be reminded of each other since both MCs are struggling manga-ka who create shoujo manga (which seems to be lampshaded a bit) and try to support their sibling(s) and assistant whenever they can.
