Title: Smile, Mei
It was Easter when Yuzu and Mei decided to take a little walk to a nearby park. The two just got together after a long while and somehow the younger girl is in a deep thought of how to "date" her blond lover without the help of the notebook Yuzu created.
Along the way they heard a camera snap not far from where they are - a father cheering his daughter beside Yuzubocchi. "Smile, Mei!" said the man who happily took the picture from a girl hugging the side of the big mascot.
It was a coincident that she had the same name with the raven haired girl. Yuzu on the other hand also came up to cheer up Mei.
"See, Mei? – So smile!" Yuzu said while pointing to where the father and daughter at. Her smile is as if she wanted to make their little walk date happy and light.
Mei on the other hand remained silent. Only tucking strands of hair at the back of her ear and a little blush are her answer. It's true that they are now together and officially became lovers. But in this scenario, Mei is still uncomfortable because she doesn't know how to be "lovey-dovey" with Yuzu (publicly).
"Kawaii!" mentally screaming and smiling, Yuzu finds it cute that Mei is still consistent of hiding her feelings to others but through the eye of the blond her action is louder than words which only motivates her to push a little teasing with the younger girl.
"Aww Mei! Can't you smile for me please? You know, being serious and all will just create early wrinkle in your face" pouting cutely by Yuzu.
"I don't see the point smiling. I am not the "Mei" that he is pertaining to." a straight up reject to her request.
"But I also asked you to smile. Can you please at least show that part of you with me?*wink*"
"..."
The two are now at a staring contest as if Yuzu is begging Mei for a smile and Mei clearly saying "NO". It took a minute or two to break the stares. Yuzu resigned and accept her defeat with her ice queen. They continued to walk together but this time Mei made her shyly moved and hold Yuzu's hand as a consolation to her request. Yuzu was surprised with this action but did not even dare to say a word because it might just cause Mei to let go.
Three hours passed; they went to eat at a local cafe, bought school stuff for Mei, and newest fashion dress for Yuzu. Everything went fine and not a single problem so far...
On their back to their apartment, they saw the same Yuzubocchi mascot on the street. Yuzu being a fan, run towards him and took pictures. She noticed that Mei is watching her childish act. She immediately pulled the raven haired girl close to the other side of Yuzubocchi to take another picture.
"Yuzu... I can't. This is a silly!" Mei protested, trying to get away from her lover and the mascot. But Yuzu grab her wrist to make her stood still in place.
"C'mon Mei! It's Yuzubocchi! I will not let go of you unless you comply!" said the blond girl demanding a picture opportunity of them.
"*sigh*...make it fast" Mei looked (annoyed) at the camera as she is waiting for it to capture a picture and get over with.
"Hey Mei, come close a bit will you?" Yuzu whispered at the back of the mascot. Allowing the other girl to lean forward to hear what she will say.
"What is it?"
"Smile, Mei!" repeating those same words that they heard earlier, as she said those words, Yuzu give Mei a quick kiss on her lips before returning in front, posing for the camera leaving the raven haired girl blushing at the back. Slowly, Mei also emerged from behind. Yuzu took their picture, thanked Yuzubocchi, and left.
Side by side, holding hands. Both girls are silent on their way home. Mei – guiding Yuzu as to not stumble or get lost walking, while Yuzu is busy with her phone with the happiest smile on her face – looking at the picture you would see Yuzu hugging Yuzubocchi with a huge grin while Mei showing a simple smile with a natural blush on her face. She made the current photo her screen wallpaper because it's rare to make the younger girl smile in front of the camera and with every chance possible Yuzu gets to fall in love with her tsundere girlfriend more. The only word she describe this now is:
"Perfect!"
