You must complete the sidequest “Kukiel is Missing” before this sidequest becomes available.

If you visit the Bazaar, you’ll find the man sitting at one of the tables who will tell you about a moaning noise that is being heard coming from the Knight Academy restroom at night.

Return to the Knight Academy and sleep until night. Then, head down the hall towards the restroom. You will begin to hear a voice. When you try to enter the restroom, the spirit inside will ask for any kind of paper.

Return to your room and sleep until morning. When you leave your room, you’ll find Cawlin in the hallway. Speak with him to learn that he has written a love letter (a piece of paper) for Karane and agree deliver the letter.

During your conversation with Cawlin the voice from the restroom will be discussed. Cawlin will specifically tell you not to give the letter to the spirit inside the restroom. Even so, the game gives you the choice of where to go from here. You can either deliver the letter to Karane or give the paper to the spirit in the restroom.

Give the paper to the Spirit

If you choose the give the paper to the spirit, you will receive five Gratitude Crystals and the sidequest is over.

Cawlin will be distraught.

Deliver the letter to Karane

You will find Karane in the classroom inside the Knight Academy. When you speak with her, she will mumble something about Pipit, but give her the letter anyway. Karane is flattered, but is curious what Pipit would think. She doesn’t make a decision of who to date at this time.

Head upstairs and find Pipit! When you tell him about Cawlin’s letter, he realizes that he loves Karane and asks you to return to Karane and find out her decision.

When you find Karane again in the classroom, you’ll witness a confrontation between Karane, Cawlin, and Pipit. In the end, Pipit and Karane are together and you will receive five Gratitude Crystals for helping Pipit realize that he is in love with Karane.

Cawlin will be distraught.
