It's absolutely alright, as long as it doesn't put any more pressure on you!
Awesome stuff :D It should be pretty easy to add :3 The hard part will be remembering to actually do it when it comes around to adding the next volume, haha. I've made a checklist of things to change and add when it comes to releasing volume 03 though, so I've put it on there to remind me!
It really is so, so cute ^-^
