Haru Kirishima
About
Haru is well known for being able to master anything he sets his mind to in at most 3 hours, and that extends to not dating someone for more than that either. He helps develop "Tokimeki Utopia", an online virtual reality dating sim for his brother's company, and agrees to debug it prior to launch; expecting things to go smoothly, he is puzzled when an NPC doesn't respond the way Haru is used to being treated by others.
