Law sat in his room in his submarine. He was reading a book on how the heart works. He had read it a hundred times but it was something to do when he was alone. It had been a while since something exciting had happened and it had been a few months since they had taken down Doflamingo.

A knock on the door aroused him from reading. "Come in." Shachi opened the door and entered. He looked slightly worried and a little nervous. "Are you alright?"

"W-We have a p-problem." Law was confused. Was there damage to the ship? Was there an enemy after them?

"Um…"

"Shachi! Spit it out!" Law was slightly panicked. His nerves were on alert.

"The S-Straw Hat P-Pirates are close t-to us. They want t-to meet up." Law could tell there was worry in his engineer's voice. They always had problems when they were with the other crew.

"Do you know what they want?" He was a little worried that they wanted to meet up. Was something wrong?

"Someone on there ship is in need of medical attention and they found out we were close," Shachi answered.

"Chopper's a good doctor. Why can't he tend to them?" Shachi shrugged. He placed his book down. Shachi stood there.

"Do you know who it is?" The other shook his head. Great. Not only do I not know who it is, I don't know what's wrong with them. Law rubbed his temples. This is going to be bad. He was sure of it.

The Straw Hats docked next to them. Law met Nami on the deck. "You said that you had a person in need of medical attention." The girl looked slightly guilty. "What's wrong?"

"We have no idea," she admitted. "We were on an island and went to explore it. We took our eyes off of Luffy for five minutes and he came back looking pale. We questioned him and he was really out of it." She looked slightly annoyed. "Then he started saying that he wanted to see you and asked hundreds of times where you were. He started running a fever and didn't want to eat anything. Chopper gave him medicine but it didn't seem to work." She looked at him with worry in her eyes. "Please help him."

Law was worried. He had never heard of Luffy not wanting to eat. "Bring him to the infirmary. I'll take a look at him and find out what happened." Nami and the rest of the crew looked relieved. They didn't think that he would help.

Law got some medicines ready for Luffy's fever. Zoro came in carrying Luffy over his shoulder. "Please place him on the bed. You can join your crew in the dining hall with everyone. I'll inform you guys when I find out what's wrong." Zoro nodded and left.

Looking down at Luffy, Law could tell something wasn't right about the kid. He placed a hand on Luffy's forehead. The colour quickly returned back to his skin starting from where his hand was and continued throughout his body. Luffy's eyes opened to stare at Law. The look made him uncomfortable.

The change made him confused. "How are you felling, Luffy-ya? Are you in any pain?"

"I feel fantastic. You look really handsome." Law almost fell over at the compliment. He never got compliments.

Ignoring the comment, Law continued. "When you were on the island with your crew, what did you do?" Luffy thought for a moment.

"I walked off from the group and found a fruit. It was really delicious," Luffy said with a grin. "And then I felt this notion to see you again."

"Luffy-ya, what did this fruit look like? Can you tell me?" Law left to find a book he had on the fruits of the world.

Luffy looked a little disappointed and a little paler when Law left. "It was in the shape of a heart, greenish blue, and it had four leaves on the stem."

As he flipped through the book, Law stopped on a page. The same fruit was shown on the page. He immediately dropped the book with wide eyes. "Is something wrong, Traffy?" Law looked up at him with slightly pink cheeks and wide eyes. Luffy was pale again and all of a sudden collapsed.

The room went quiet as Law entered the dining room on shaky legs. He made it over to a table and Bepo set down a cup of coffee in front of him. "Do you know what's wrong with him?" Sanji asked as he walked toward him.

A nod was his response. "Are you alright, Captain?" Penguin asked. Law hid his face as he shrugged.

"I want everyone to join me in the infirmary after lunch," Law spoke in a quiet voice as he picked up his coffee and left. Bepo announced to both crews of Law's request.

Everyone was gathered in the small room. Law sat on a chair next to Luffy. "What's wrong with him, Law?" Chopper was the first to break the silence.

Taking a deep breath, Law explained. "On the island that you guys decided to explore, there is a fruit that Strawhat-ya had eaten." Everyone looked confused.

"If he just ate a fruit, it shouldn't do this unless he is poisoned," Usopp said. Law shook his head.

"This particular fruit brings out emotions and desires of a person that they keep on the inside and don't show to others. The reason he is showing these symptoms is because he was not around the person which these emotions or desires revolve around."

"Do you mean that we have to look around the entire world for someone that only Luffy knows?" Robin asked.

"No. Watch this." Law stood and placed his hand on Luffy's forehead. The same reaction happened. Everyone stared with wide eyes.

"What does this mean?" Nami asked. It was fascinating to her. Law sighed.

"What did he talk about the most before you landed on the island? I may be able to explain better if you can understand more."

"Now that you mention it, Luffy did talk about you a lot. He had wanted to meet up with you for a while now. But what does that have to do with it?" Franky said. This surprised the doctor.

Chopper realized in a second. He looked to Law for permission to speak. Getting a nod as an answer, Chopper explained what Law was trying, or to embarrassed to say. "The reason Luffy was not around the person was because he was not nearby. Law is that person. As long as he is in the same area as Law, then he will become normal again." Everyone stared at Law with wide eyes. "I must ask, though, how long will it take for him to get better?"

This was the difficult part. "That depends, how long has it been since he has had the symptoms? If he were close to the person when it happened, then it would take about a day or two. If longer, then that is double the time that he spent away from them." Everyone in the room paled.

"It, um, has been about a week since that has happened," Zoro confessed. Law looked defeated. That would mean he would have to spend two weeks with him.

Law pinched the bridge of his nose. "Hey, everyone!" The outburst made all the occupants jump, especially Law who was right beside it.

"L-Luffy? Are y-you feeling alright?" Chopper asked. Luffy looked better but couldn't be certain. He looked to everyone. He couldn't find Law who had hidden behind Bepo.

"Where's Torao? He was just here a second ago." Law shifted out from behind Bepo to confront the problem.

"Let's go get something to eat! We'll let Luffy and Captain have a moment." Penguin ushered all but Law out of the room. He felt uneasy as he was left with a problem.

"Are you alright, Strawhat-ya?" He didn't get a reply other than Luffy pulling him down onto the bed with him. He laid there on his chest feeling very uncomfortable.

"You smell good, Traffy," Luffy stated in a sleepy tone. "Take a nap with me." Law didn't object and just toed his shoes off. Luffy continued to hug Law to his chest and breath in his scent.

The beat of Luffy's heart was lulling Law to sleep. His eyes started to close and his breathing evened out to a steady rhythm instead of the panicked one. "I love you, Law," was the last thing he heard before the darkness took him into dreamless sleep.
