Lillianna's manga / #Sadist(2)

This is really bittersweet, there's a lot of sad but also a lot of fluffy happy chapters. This deals with grief, loss, loneliness, war, etc. Maybe don't worry about the romance tag, it's mainly hinted at for MC or shown involving a bird person and a queen. The epilogue does hint there's a future romance for the girl though. There are depictions of self harm so be cautious reading this, though the chapter warns you it's happening.
