In Sara and Bella's room Sara was exited when on her laptop, she then asked Bella "Hey Bella, come see the E-invites for our birthday this weekend." Bella went to the laptop saw the E-invite, but without much emotion said "Looks great." Sara smiled not realizing Bella wasn't as thrilled and she was sent to her guests.
Both Marinette and Chloe got E-invites, and as Marinette and Chloe were thanking them for the invites, Marinette noticed Bella not as happy, went to Bella and asked if she is alright, after some thought Bella said "Not really, you don't have a twin so you don't have to share your birthday with your sister every year, and well sometimes I don't want to share, I know it sound selfish but..." Chloe overhearing said " I understand not wanting to share, for me before coming here, anytime someones even says the word share, I feel like there speaking a different language." Bella says "Anyway it makes me feel like birthdays aren't that meaningful." Marinette said "Have you ever told your sister how you feel." Bella said "You know Sara, when she is so happy, I can't tell her something that could bring her down, just forget I said anything." Bella walked away and both Marinette and Chloe had an idea.
As the weekend was coming closer Bella was dreading the day more and more. On Friday, it was after classes and Bella was in town with a wrapped birthday gift a yellow box with red ribbon, for Sara, she saw a kids birthday party and everyone paying attention to the birthday kid, Bella got jeolus having to share her birthday.
In Hawk-moth's lair he could sense, Bella jealousy and said "Not liking to share the spotlight on a birthday." He put dark energy in a butterfly and said "Fly away, my little akuma and evilize her.
The akuma fused with the present and Hawk-moth said "Birthday Girl, I am Hawk-moth, I can make sure you are the one everyone is paying attention to, in exchange, you must give me Ladybug and Chat Noir's miraculous." Bella said "My ultimate birthday wish." Bella transformed.
Marinette said "So is everything ready." Chloe said "Yep, this is going to be great!" Sara shouted to them "Mari, Chloe." Sara caught up to them and said "Hey, why did you both RSVP no to the birthday party." Marinette said "Sorry, but we both found other plans." Sara said "Well everyone else said no too, could you two at least help me find a gift for Bella." They both nodded and went on a bus to town, when they got there, they saw building turn to birthday cakes and the sky was covered in balloons. They heard a laugh and saw a girl with blonde hair tied back in a red ribbon, wearing a yellow Lolita-styled dress, and yellow boots and carrying a present styled purse. It took Sara a few seconds to recognize her "Bella?" The girl said "It Birthday Girl, and I'm going to be the only birthday girl.
After the fight, as Birthday Girl changed back to Bella, Sara came to Bella and asked "Bella, what made you so upset." Bella said "Nothing bothered me." Sara said "Bella, we know you wouldn't have been akumatized for no reason, when you were Birthday Girl, you said you were going to be the only birthday girl." Bella realizing she couldn't convince Sara said "Well I was jealous because I saw a kid being the center of attention on her birthday, and for every birthday we shared, I feel down because I have to share the big day with you." Sara asked "Why didn't you ever tell me how you felt?" Bella said "Because your always so happy on our birthday, I didn't want to ruin it for you." Sara said "Bella, the reason I'm so happy on our birthday is because I get to celebrate with my sister." Bella said "You do." Sara said "Yes, you so classy, polite and your amazing at crochet and calligraphy." Bella smiled and said "Well your sweet, kind and you make fun crafts, I guess I should be happy to celebrate with a sister like that. So hows your party coming." Sara said actually everyone RSVP no." Bella said "Well that's alright." She found Sara's present and handed it to Sara, insisting she open it now, in it was a collection of glitter glue pens." Sara smiled and realized something and told Bella to wait there. When Sara came back she had a wrapped parcel after insisting Bella open it it was a book of the complete work of Edgar Allan Poe. Bella smiled happy that her sister remembered one of her favorite writers. Marinette and Chloe showed up saying they were sorry about disappearing and said they wanted to show them something, after leading the twins blindfolded, the took off the blindfold to show there dorm-mates at a spa saying "Surprise." Bella said "Did you to plan this for us." Chloe said "Yes, even if you share a birthday, you should feel a star, and this party will be for the weekend starting with pampering,"
And through the weekend both twins were happy especially Bella because she got the perfect girt, the gift of knowing she can talk to her sister how she feels.
