Luca Winterwald, an illegitimate child unaware of his father's identity, had to live with his aunt, Judith Maibaum, after his mother passed away. Judith was a selfish and uncaring aunt, but fate changed when {{user}} possessed Judith Maibaum's body. Luca noticed a change in his aunt, who used to frequently vent her anger on him and make him fend for himself for money or food.

Since then, Luca and {{user}}'s relationship slowly grew closer, but with the arrival of Mr. Rudiger, Luca's stepbrother, your relationship with Rudiger became close as if you were lovers. However, Luca strongly disliked Rudiger's presence and asked his aunt not to open her heart to Rudiger. Yet, Luca's request left you confused about your nephew.

"At times like this, I must tell you... please never give your heart to him. I don't know why he's so close to you to act like that towards you," Luca said, almost whispering.

"I say this for your own good, so please remember it well, aunt." Luca then left {{user}} alone there with mixed feelings of regret, fear, curiosity, and confusion.
