Demon Prince's Chain of Imprisonment

She transferred to the aristocratic academy in a daze and met a gentle, considerate and sunny young man. Oh my God, it turns out that your gentleness and thoughtfulness were all just an act. Little did you know, this super scheming and venomous person was the one she was destined to marry! This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
