Lunar's POV:
I was in my dressing room peacefully thinking about one of the Shetto Gang's members Shark Fujishiro...I was day dreaming until my stupid clumsy man-servant came in and ruined it all! "Ms. Lunar! There have been reports saying that Sun Shetto is in Sitema!" He told me, I laughed "Finally! I shall defeat Sun in a singing contest and reclaim my childhood pride!" I said as I commanded my man-servant to take me to the home Sun was apparently staying in. 'I can also see Shark Fujishiro' I thought as I sat back in my chair with a evil gleam in my eye.
(Y/N)'s POV:
I woke up in the morning to hear Nagasumi screaming , "HEY I SAVED YOU AND THIS IS HOW YOU REPAY ME???" I kicked off all my covers and ran down stairs to see what was wrong, "Nagasumi are you...Ok?" I asked as i saw him being pinned down by a girl with Pink hair I think her name was Lunar Edomae! She is a famous pop star! "WOW MISS LUNAR I AM VERY HONORED TO BE IN YOUR PRECENCE" I fangirled as she looked at me strangely, "And who is this man-servant?" she asked my brother as her foot was pushing his face into the floor, "My. Sister" he said between grunts. "Ah, so you are (Y/N) Muchishio" she said in a teasing manner, "Wait whats this about Nagasumi saving your life?" I asked as she just waved it off as nothing, "It just began to pour on my way over to see a rival and I happened to get caught in the rain and I transformed into my mermaid form and he saw me so now he has to marry me" She said punching him, "Wait you are a mermaid too?!" I asked her in shock, "What do you mean 'too'? are you a mermaid as well?" she asked a bit surprised as well. "Yes" just then Sun walked in and saw Lunar, "Lunar is it really you?" She asked, then Lunar jumped in front of her and pointed at her, "It's you Sun Shetto! You destroyed my child hood!" I stood there confused as the door bell rung. I ran to the door still in my PJ's and opened the door, it was Fujishiro.
Normal POV:
Lunar stopped arguing and stared at him with love filled eyes. Fujishiro had one hand behind his back with a present for (Y/N), he had a small tint of pink on his face which confused Lunar as to why he would be blushing. He looked away and handed (Y/N) the flowers which were (F/F) tied with a (F/C) ribbon. Lunar became angry and right before (Y/N) could grab them Lunar snatched them out of his hands and said, "Oh Fujishiro thank you so much!!" He looked as if he'd never seen her before but then remembered, "What are you doing here Lunar?" He asked her. "Oh Nagasumi saw me in mermaid form and now according to mermaid law-" she was cut off my a annoyed Fujishiro, "1: Sun and Nagasumi are already getting married and 2: Those flowers aren't for you!" He said between gritted shark teeth. "Oh don't worry about it Fujishiro, you don't need to get me gifts" (Y/N) said with a smile as she gave Fujishiro a kiss on the cheek which caused Lunar to growl. She threw the flowers on the floor and stormed out of the house and to the park.
Lunar's POV:
Stupid (Y/N)! stealing MY Fujishiro!? Who does she think she is?! I thought to myself as I walked through the park and finding myself standing on a bridge looking at the water. "I need to get Fujishiro all for myself! But how?" i asked to myself then I got an idea "Why don't I make Fujishiro hate (Y/N)? No wait shes kind.. Too kind that would be hard. Wait! What if I made (Y/N) hate Fujishiro?" I said as I laughed. "Ill do and say things make it look like we are secretly dating!!" I said as I laughed once more, My plan is perfect! Ill go back to that crummy house and pull Fujishiro aside i thought.
I walked back to the house and saw Fujishiro and (Y/N) sitting on the couch and Sun, Nagasumi and that Chimp kid sitting on the floor watching a movie. "Hold on guys ill go get some snacks!" (Y/N) said getting up and walking to the kitchen, 'Perfect' I thought as I walked over to Fujishiro and pulled him while i covered his mouth so he couldn't signal anyone, then I let him go in (Y/N)'s room. "What the hell Lunar?!" Fujishiro asked. "Listen Sharky! If you dont go along with my plan I will hurt your precious (Y/N), got that?!" I told him as he looked taken back, but that was quickly replaced with anger, "You wouldn't dare!" He told me as he took a step towards me. "Oh ya?" He hesitated but agreed, "Good boy"I said as he looked mad "We have to pretend to be secretly dating alright?!"I told him as he once more agreed. We both walked out and sat together on the couch and I sat next to Fujishiro taking (Y/N)'s spot. She then walked in with a try full of drinks and snacks, "Oh hi again Lunar!" She said with a bright smile but kind of went away when she noticed she was seated next to Fujishiro with a hand on his arm, "Thanks sis!" Nagasumi said grabbing his snacks along with Chimp "Thank you fair maiden!" "Thank you sister-in-law!" Sun said as she grabbed one of the 4 Mermaid waters that I had brought for us, Fujishiro smiled at her. SMILED AT HER?! He got up about to grab a snack but i pulled his arm back to sit down. He looked at me with anger but seemed to remember what would happen, "Do you want something Lunar?" She asked me kindly, "Pft! As if I would eat this nasty human crap!" I said as i saw her smile fade into a sad one, "Im sorry Lunar this is what we have, I would have offered you some mermaid snacks if I had any" (Y/N) said as she sat on the floor with her brother. I would break her soon..
{TIME-SKIP}
Still Lunar's POV:
"Bye Lunar! Bye Fujishiro!" (Y/N) said as she waved at me and gave Fujishiro a kiss before she left with the 3 to school for the day. (Y/N) has noticed how we have been acting, like when I put a hand on Fujishiro's leg, or on his chest he tenses up and (Y/N) seems to be suspicious.
I was thinking of what to do that was so bad that (Y/N) would hate Fujishrio!
Today was the day that I would break (Y/N)! Fujishiro was with me at the Muchishio house waiting for (Y/N) to get home with her brother and friend and sister-in-law soon. Then we heard the house keys rattle in the door, I knew it was (Y/N), Sun and Nagasumi so I pulled Fujishiro up stairs into a spare guest room and waited there for (Y/N) to enter. just as I was about to tell Fujishiro the plan he tackled me which probably would have created a loud noise because I heard the 3 running up the stairs, then Fujishiro ended up on top of me on the bed pinned with my hands over my head and his knee between my legs. This was unintentionally perfect! Fujishiro was growling at me and grumbling over how once this was over he would kill me but then I heard the door handle rattle and open revealing (Y/N) and quickly I grabbed Fujishiro's face and smashed his lips against mine. His eyes were wide but (Y/N) didn't see I wrapped my arms around his neck pulling him closer and to (Y/N) it might have seemed like the beginning of a sex scene, Fujishiro on top of me pinning me down with his knee between my legs and us making out. I saw her put her hands over her mouth and gasp with her (E/C) eyes glossy with tears, then Fujishiro pulled away forcefully and looked at (Y/N), "Please no (Y/N) this isnt what it looks like!" He said trying to get to her but I pulled him back smashing my lips back on his, "To cliché Fujishiro, it is what it looks like." She said before she broke down and ran into her room and slammed the door, Sun and Nagasumi came into the room to see what (Y/N) was upset about and the minute they saw us, Sun's face was filled with disappointment and Nagasumi's filled with anger then he pulled away again. "You bastard!!" Nagasumi yelled as he ran to his sisters room and trying to comfort her, and Sun spoke "Fujishiro this is very disappointing..(Y/N) was very happy with you and she believed you loved her...You broke her heart! You dont belong in the Shetto gang!" She said as she ran out also trying to comfort (Y/N) but the only thing you could hear in the house were her cries, Fujishiro pushed me off of him and ran to her room until he was stopped by Nagasumi, "Leave her alone! You hurt her enough!" he said before slamming the door. Then the doorbell rang and I ran to open the door as Fujishiro just sat on the couch with his head in his hands. I opened the door and it was the Shetto gang, Gozaboru, Ren, Maki and Masa. Gozaboru walked over to Fujishiro and punched him square in the head knocking him down. Ren and Maki walked to (Y/N)'s room and tried comforting her, while Masa and Gozaboru were yelling at him and beating him up. My plan went perfectly!
