Natsu was in the Guild in the kitchen with Mirajane he asked her to help him to make a strawberry cake, which she smiled and nodded. so the two baked a cake for her iced it and Natsu put some strawberries made into a jelly in the 3 layers it had vanilla frosting and powdered sugar strawberries on the top and the sides and top had frilly patterns.
Natsu then walked to her window of her Apartment in Fairy Hills, he then jumped to the window seal and looked in and saw her reading a Smut novel he knocked on the window lightly with his head since one arm was on the ledge and one was under the cake.
Erza turned with surprise to see Her boyfriend outside her window and opened it and Natsu crawled in carefully.
"I hope you have a reason for arriving like that" Erza stated with a sharp glance.
"Uh yeah I was wondering if you liked to go on a date with me?" Natsu asked normally, since he went on the first date with Mirajane he was more confident now "if your not too busy" he said.
"Hmm?, I was getting bored so sure" Erza smiled
"alright meet me outside" Natsu as he walked to the Window making Erza grab his shoulder.
"leave like a normal person" Erza ordered pushing him to the door.
"Right" Natsu grinned he then used Hidden Flame to turn invisible to avoid the Cranky lady in the Inn, he then appeared back outside and used his hearing to hear and listened to her footsteps leaving her room and closing her door and locking it and then disbursed the spell on the cake, the two sat on the ledge of Natsu's secret spot having a picnic sitting on a blanket
"Kind of old fashioned but it's nice" Erza smiled "and it's nice to be treated like a lady not a Knight" she said looked at the blue sky and clouds.
"Yeah it's peaceful, just remember this place when you want to think and relax" Natsu smiled.
later Natsu and Erza walked back to her room Natsu smirked "sniffing the air I smell something in your room" he said.
"What?" Erza glowered and requipped a sword and barged in the room and her eyes fixed on a strawberry cake on her table.
"Surprise, thought you'll like something sweet after our first date" Natsu smiled.
"When did you place that here?" Erza gaped shutting her door and licked her lips at the cake.
"Oh I brought it here when I visited Mira helped though" Natsu admitted.
"Aw thank you" Erza hugged his arm, later the two enjoyed the cake on her couch talking about adventures they had in the past and recently.
"Ah don't mention it" Natsu told her, Natsu noticed she didn't wear her armor when they were walking outside or when she was around him in private moments.
"Thanks for today Natsu I'm glad you choose me for one of your mates" Erza smiled hugging him tightly.
"I'm just glad you and Mira excepted to share me" Natsu smirked then pecked her on the lips "whoop sorry too slow" he smirked.
"Oh you want to play that game" Erza smirked evilly and crashed her lips into his and wrapping her arms around his neck as he wrapped his around her waist as she pushed him laying on the couch as the two kissed on it, later the two fell asleep on her couch enjoying the other's company.
