East Rhapsody (kinda obv?) but also Christmas 2023 - it's not translated yet but I read it and I must say I cried, because it feels like it's an important event for Heath, where he gets a little step forward into accepting himself as a wizard
As for my fave card art... It's hard to choose...omg. i totally love Birthday 2022 and 2023 card (though I dislike the outfit on this one but his expression is...so..good! - I have it on phone wallpaper 🤭). I also have a soft spot for Summer 2021 card and 3rd Anni (it was my first card of Heath besides the starter gacha~). Sorry, cannot pick one, I love so many 😭
