This has got to be the cutest of all the ones I've read so far :3 It's absolutely adorable, both in terms of the writing and the artwork ^-^ I'll put the rest below spoilers just in case!
SPOILERS
So yeah, awww, adorableeeee x3 I would definitely give Mothdude a hug! And that was such a heartwarming moment to see onscreen. I loved the slurping sprite and the hugging, but I wasn't expecting to be bowled over with even more cuteness at the end when they all had those Mothdude masks on at the concert xD Pretty sure I aww'd out loud, haha. They all looked so cute playing their instruments together. And those 'photos' made me chuckle. It's just so wholesome with a lovely bittersweet ending. Also reminds me of when my brother was younger and used to hang out with his friends and go skating :3 Oh, and I loved the chapter select design too!
On a side note, I love moths in general x3 They're cute, haha. And I will now be disappointed if I don't see someone dressed as a Mothdude type character this spooky season!
