Question: Does Ideum's crush appear later in the story? Author: No, the crush does not appear in the main story!
so we can exclude that jiseong is the crush and a theory that ideum just forgot about his face or name. jiseong could have been another classmate who noticed ideum, but ideum never did. hence knowing ideum's name before their introduction to each other.
On a side note
Favorite Positions: Jaeyi: missionary and sitting Ideum: missionary and riding
