The next day, Luigi and Daisy threw an engagement party with Mario and Peach at the Mushroom Kingdom, of course (against Daisy's will) at Peach's castle. Peach and Mario greeted Luigi, and Daisy came in behind, as Peach said "Welcome Daisy! Congrats!" and hugged her cousin. Mario, looking a bit uncomfortable greeted Daisy, trying not to make eye contact.
They feasted at the dining hall, and they all were laughing and talking, but Mario couldn't stop staring at Daisy uncomfortably. Then Peach raised her glass of red wine off the table and said "Cheers to Daisy and Luigi, for they will spend the rest of their lives together!" Everyone raised their glasses, but Mario did cheers with everyone but Daisy. Daisy kept her glass up for Mario, but he was too busy eating for him to notice, so she slowly placed it down.
Daisy saw that Luigi started to notice Mario's actions, and he started whispering with him, but Daisy heard the whole conversation. "What is going on with you today?" Luigi asked Mario. "Nothing is going on, I'm fine." Mario replied. "I saw the way you were behaving with Daisy, so can you stop with that?" Luigi asked. Daisy blushed a deep red, but everyone was too focused on the food to notice. "Umm… It's because you are about to marry the girl of your dreams, and I'm nervous for you, Luigi." Daisy took note of Mario's little lie, and decided to tell Luigi before it got more awkward with lies.
Suddenly, Peach spilled the wine on her pink princess dress, and gasped. Mario stood up frantically, and followed the blonde princess toward the nearest bathroom in the castle. Daisy almost rolled her eyes, but she knew Luigi would see and scold her. As Mario and Peach left, Daisy found it the perfect time to tell Luigi.
Luigi started to follow Mario and Peach to help, but Daisy called "Luigi, wait!" Luigi turned around and asked "Yes, Daisy?". "I need to tell you something…" she replied. Luigi sat in the dining chair next to her, and looked at her in the eyes. Daisy laughed nervously and said "Yesterday, you know, after our big day?" Luigi nodded and said, "Go on…" "So I was at my castle and I heard a knock on the door, and I expected it to be you…" Luigi looked at her, with wide eyes. Daisy said, embarrassed with her face red, "I just had my underwear on and, well…" Luigi came close and put his arm around as she finished, "It was Mario." Daisy hugged her knees and buried her head in embarrassment. "Ugh! I swear I thought it was you!" she winced. Luigi hugged her and lifted up her head, then kissed her on the cheek. "It wasn't your fault, Daisy… Mario should've said something when I asked him." Daisy kissed him back and said "Thanks for listening."
Luigi moved his seat closer, and Daisy mischievously whispered in his ear "You know, you could see me like that if you want…" Luigi started sweating nervously and said "Daisy, you don't have to-" "I know your nervous Luigi," Daisy said, poking his nose. Mario and Peach walked back in, Peach's dress good as new. Daisy and Luigi both were in silence, both sitting close to each other.
Daisy started turning red, not knowing what to say, and Luigi started sweating. Daisy knew she had to tell her best friend, Peach, but she couldn't face Mario, or things would get worse. "How about we get some fresh air?" Luigi asked, saving Daisy from an awkward silence. "Mario, I need to talk to you." Daisy's heart started pounding. Crap, Luigi, I didn't ask you to talk to him! Everyone went outside, and Mario gave one look at Daisy to know she told Luigi.
