The male lead is very similar to Sang Yan in that he goes out of his way secretly to do things for the female lead to catch her attention or just to make things easier for her. He also doesn't push her in any way to fall in love with him and just waits and cares for her in his own way until she heals.
Basically the same plot, except the female lead is a badass firecracker and is talented in developing games in her own right. This drama is also a sort of enemies to lovers as well and it's adorable to see them fall in love.
If you want to see another age-gap romance (the age gap isn't emphasized as much though), and you want to see another green forest male lead doing everything for his girl even while just pursuing her, then make sure to watch Shine on Me.
