HOW DO I NOT KILL ALEX AND DIANA :(
Viewing post in Magical Warrior Diamond Heart [Common Route] comments
Alex needs to be at yellow hearts/best friends level to get through his version of e13 otherwise you'd have to hangout with someone else (Right now, only Liam is available but Ethan should be available soon this month too)
If Val has a crush on Alex though, he needs to be at pink hearts. OR he can be at green hearts if Liam is at pink hearts
