As the title says! I just want it to be seamlessly written into the story, but really not the main focus. Two examples of subplots I really like are Ninth House by Leigh Bardugo and The Poppy War series by R.F Kuang. But please not only YA/fantasy! I just read The God of The Woods by Liz Moore and really liked the subtle romance subplot hidden in there.
