Somehow, Designated Love reminds me of Miss Gu's 100 Confessions! The fact that it involves an immersive AR game and that it is all because of the male lead.

- FL lies about who she really is
- FL hides her actual "poor" life/past and pretends to live a "cool" life
- FL has a questionable group of friends
- Someone close to the FL knows the truth
- ML personality is kinda similar

- The ML and SML both have a close relationship to each other
- The Emperor favours the FL and is jealous of the FL's relationship with her first love
- FL is smart/strong and conquers the imperial harem, fighting for justice
