Invitation Letter to the Love Room

The Invitation Letter to the Love Room is a Tower item kept by Chae Nayun because it offers a way to summon Kim Hajin when they are otherwise separated.

History

Preserved invitation

Nayun receives the level-five invitation and immediately associates its summoning function with Hajin. She repeatedly considers using it but holds back. Before leaving the Tower she converts it into an effective good, allowing her to carry the physical letter on Earth, where she carefully checks that it remains in her possession. (Chapters 196, 207, 216, 232, and 244)

Emergency activation

During the fight at Park Hanho's laboratory, Nayun activates the invitation despite being inside a battle zone. The normal description prohibits battlefield use, so the item cannot forcefully summon Hajin. Instead, it creates a portal and warns him of the dangerous location, leaving him to enter before the portal disappears. The source does not clarify whether the letter survives this activation for another use. (Chapters 294 and 297)

Abilities and properties

• Normally summons a chosen Player to the user's location, provided the user is not in a battlefield. (Chapter 196)
• Effective-good conversion allows the letter to leave the Tower. (Chapters 216 and 232)
• In a prohibited battle zone it creates a temporary portal and warning rather than forcing the target across. (Chapter 297)
