Diego is an open mind guy, I dont think we would be jealous over anything. They were buddies, I don't think he would jealous or something 😁
After you completed Diego's route, head on to Tai's Route... I can guarantee you the emotional rollercoaster. You will love it for sure.
FYI: pls prepare some tissues while going that Tai's Route because there're no tears left to cry. 😁
