Sooo glad you loved the game!!! yay <333 !!!
For Zach, nothing is planned as of now, since he isn't actually a confirmed Love Interest. But a lot of people on tumblr are asking me to make him one, so maybe in the future! If he were one tho, it wont get to that point as quick as with Yuki. This is because you have to get Zach to trust and love you, unlike Yuki who is already looking for excuses to be near you lol.
