Oyome Ni Ikenai!
age gap of 10 years
Freezing
The infamous strongest girl in the school. story-wise, it's not that great. the development is ..okay I guess? But i like the idea and the concept, as well as the character design. Bridget maybe strong (if not the strongest) but she is like a wang-da (outcast) with the way the other students treat her she had my sympathies. Heads up for classic wimpy guy trope. #sempai x kohai. girl is older than the guy by 2 years a few colored pages at some chapters. Note: This is a manhwa. 100% korean-made. It got really popular that the japanese publishers take note of it and published a japanese version.
Nu'er Guo Chuanqi: Shengnan Pian
#manhua (chinese) i'm disappointed on the fact that despite having a world that has changed gender roles, this main character is still an epitome of the most stereotypical shoujo heroines arounds. a nice story if i could ignore the girl and her damsel in distress self. the premise is quite promising too and i like this kind of fantasy so well, let's just enjoy the bishounens.
