Basically dude who gets bored with anything he tries after three hours (because he can master anything) goes into a dating sim he started to program a long time ago, which was now being programmed by his brother's company. He finds a character that won't fall in love immediately and is different, so he falls. Pretty standard stuff, actually.
But I felt seen by the otome side of it *sob*
