Bonus Content – Secret Signs
Welcome to the Secret Signs bonus corner – a little stash of sunshine, study goodies and cozy extras inspired by Sonja and Adon.
These are items I personally think Sonja would obsess over: yellow notebooks, sunflower stickers and more. They’re perfect if you want to build your own “sunshine meets grumpy pianist” vibe at home.

Sonja’s Sunshine Essentials ☀️
Secret Signs lives in that delicious space between storm clouds and golden light. These cozy, sunshine-tinted extras are here for rainy-day reading sessions, comfort re-reads and building a space that feels as warm as Sonja does – even on the days she doesn’t feel that way herself.
Sonja’s Study Notebook
This sunshine-yellow notebook is where Sonja tracks the important things in life – like cinema dates with Zaine and dance classes with Adon.

Sonja’s Annotation Set
Sonja might cause chaos in Adon’s flat, but her notes? Immaculate. Colourful annotation tabs keep Sonja’s margins perfectly organised.

Sonja’s Aesthetic Stickers
Sonja has a shameless sticker addiction – Zaine found out the hard way, but Adon smiles every time a tiny sunflower appears on his notebook.

Sonja’s Headphones
Sonja is rarely without her favourite coloured headphones – a birthday gift from Zaine. She put a small sunflower sticker on one side. (They’re exactly the pair I own).

Sonja’s Marker
Annotation tabs aren’t enough for Sonja, so she always adds pastel markers to the mix, and frankly – who says you have to pick between tabs and highlighters anyway?

Sonja’s Bag
Sonja’s favourite bag is a tote with Van Gogh’s sunflower print, combining her favourite artist with her favourite flower. The perfect bag for her bookshop visits.

Study & Language Nerd Things 🌻
ASL Stickers
When Sonja couldn’t speak and was feeling low, Zaine cheered her up with ASL stickers – and that was all it took to spark a lifelong sticker obsession. Long live, Zaine!

ASL Puzzle Book
Sonja loved learning sign language through word puzzles. Even now she still loves solving puzzles – if it’s crosswords with Zaine or jigsaw with Adon.

How to Swear in ASL
When Zaine went to buy Sonja materials to support her sign learning, she immediately picked these flashcards. At first he found it funny, then alarming.

ASL Study Flashcards for Beginners
These are some simple flashcards Sonja would recommend to anyone who wants to get started with ASL.

ASL Study Book: Dictionary
This is a book Sonja would highly recommend if you want to dive a bit deeper into the topic of ASL.

ASL Study Book: A Guide
If you want to surprise Adon at the next dinner party, this would be a great book to work through!

Adon & Sonja Domestic Moments 🫰
Adon’s fancy Espresso Cups
I couldn’t find the exact espresso cups that inspired Adon’s guilty pleasure, but he’d definitely approve of these: small, elegant and colourful.

Sonja’s Puzzle Set
When Adon and Sonja aren’t dancing they love solving puzzles together with Mr Crabs happily keepign them company beside the coffee table.

Adon’s Puzzle Set
Just as Adon and Sonja are two different painting made of the same colours, Sonja found the perfect puzzle to represent Adon.
