Boring until the end. FL and ML have nothing in common like similar hobbies or interests. FL is quite passive and does nothing until the very end. ML is yandere lite, and realizes his mistakes too quick, easily forgiven. Every plot point is wrapped up neatly with little consequence. The only interesting thing is the reveal that FL isn’t a transmigrator and is the FL persona in that world. The BL novel aspect was a side effect of her losing memories, and was never real.
