The park was full.

It was the middle of summer, and it seemed most of Odaiba had travelled o the park to enjoy the sweltering heat.

Small children ran around, chasing each other or eating ice-lollies. Other played in the pool or on the slides, jumping over random sunbathers during a game of tag.

Taichi Yagami viewed the scene and grinned to himself. This was what summer was about, enjoying yourself without a care in the world. He thought back to when he was younger, remembering all the hours he spent playing soccer with his friends or riding his bicycle.

Tai looked over his shoulder ad found his eight-year-old sister, Hikari, close behind him. He smiled gently at her. 'Feeling any better?'

Kari glances around her, and then lowered her eyes to the ground. 'But Tai…Mom said that I should stay in the house…'

Sighing, Tai rubbed his head. Somehow Kai had managed to catch a cold. That feat in itself was beyond him, seeing as it was June. Their father was at work and their mother had gone grocery shopping at some new health store, so they had put him in charge of taking care of Kari.

Tai knew he should not have brought her outside if she was ill…especially after what had happened before…he could not bear it if it happened once again. But his sister had seemed so sad. Of course he would be too, if he was forced to stay inside at summer due to a cold, something people just were not supposed to have at that time of year. But Kari always managed to catch colds. When she was younger she was such a sickly child. It seemed as though he was choosing between her health and her happiness, and happiness would win, every time.

'I know Mom said to stay indoors Kari, but a bit of fresh air will do you good.' Tai looked around him and spotted an ice cream cart. 'Hey, do you want an ice cream Kari?'

Kari seemed to ponder it for a second, and then shook her head.

Tai groaned in slight frustration.

OK, so maybe he was an idiot for asking her if she wanted an ice cream when she had a cold. But it was either that or a cheeseburger, and if his Mom found out he had fed her that she would skin him alive. His Mom insisted on healthy homemade recipes, so her kids would grow up healthy and strong. There was just the small fact that those recipes often made Tai feel sick rather than full of energy.

He sighed again.

'Oh come on Kari there must be something you want to do!'

Once again he looked around him. He could have taken her to the fields, but he deemed the kids on there too rough for her to play with. He could have taken her to the pond, but knowing his luck she may fall in or get attacked by a duck. You shouldn't think like that, jeez! Tai though to himself.

Tai smiled to himself when he noticed the children's area. Grabbing Kari by the hand he pulled her towards the swings.

The only reason he'd brought Kari to the park against their parents' wishes was because he hated seeing her so down. So…lifeless…

Kari was one of those people who was always so happy, always cheerful. She was a person whose carefree laugh would make everyone else smile…and when none of that was happening, the whole world seemed wrong to him.

Gently, he picked her up and placed her on the swing.

'But Tai…what if Mom finds out? Won't she be angry?'

Tai spotted her pink necktie. That would only make her hotter in this weather. He reached out and began to untie it.

'Mom won't find out, and if she does…I'll… think of something…' Finished, he put her pink necktie in his pocket, then reached up and removed his goggles, placing them on her head.

Kari smiled up at him as he stood behind the swing. She loved Tai's goggles. She had no idea why he wore them, or where he got them from, but he had had them for as long as she could remember. The goggles made Tai…who he was…

'OK Tai!' She said as the goggles slipped down onto her face.

Tai chuckled and smiled gently at her as he pulled the goggles back from out of her eyes.

Kari smiled once again. 'I trust you Tai.'

Her smiled meant everything to him. Tai pushed her on the swing.

She laughed…
