In one of the world's the MC uses a prop that lets the ML see a chibi version of himself that represents his 'inner emotions' but it wasn't really because MC (shou) was smarter?/sharper?/sly? or something anyways he is different than how he portrayed himself/acted as for his role? as ML's nephew or something at the time? I can't quite remember but anyways... I need help to remember this novel! Please and Thank you!
