The two main lead actors of My School President (Gemini and Fourth) are the main leads in My Love Mix-Up! too. It is a boys love romcom like My School President is so most people that love one would probably love the other one as well!
Gemini and Fourth (the main actors of My Love Mix-Up!) are a couple in Moonlight Chicken as well. Although they are the side couple, they have a lot of scenes and have a beautifully written storyline.
