this kid David is a minor character. and there really is no difference between him and Emma. they are both shy kids with crushes they have a hard time talking about with the object of their affection. sure David is obsessed with Emma but Emma was obsessed with Zak. so no difference. if the game gets continued in the future these 2 should have some scenes together. most likely they would be friends only since Emma doesn't seem to like him. he will be stuck in the friendzone, which could make him a future stalker problem for Emma. also Jenny seems like she could be using Emma to try to get closer to MC since she obviously is crushing on MC. as for Suzi, what a pshycho. might replay at some point and see where potential relationships with Lucy or Kaylah go, but for now, too many other games to catch up on.
ultimately i liked this update and really hope Darkblue continues with it in the future.
