Hello! Glad you enjoyed the game! To get Noelani's 2nd CG, try this order for choices:
- Search for shelter
- Stay alone for now
- Search right
- Stay here
- Stay alone
- Go to sleep
This is the CG I assume you're trying to get.
Also, the 1st ending for Kana IS the true ending. Not only the true ending for Kana, but also Noelani and the entire game. The only reason Noelani doesn't have a true ending is because his route is connected to Kana's story-wise. The most canon ending I intended for Noel is his 3rd ending.
