Chapter 4

Things were going smoothly for the human and his mer, Iwaizumi.

As days progressed both of them seemed to find joy in the company of the other male. Always feeling a warmth of heat radiate in their chest and through their body whenever they were in each other's presence.

A couple days passed, three to be more precise.

In total it has been nine days since he moved to the Virgin Islands and today was going to be the last week for his  coral photography assignment. After this day he shall start with the second one.

When Oikawa had come back from his meeting with the mer he had texted Koutarou to get an extension for the miniature boat he had rented previously, not forgetting to PayPal him the money for the extra days.

After their encounter it had become custom for both of them to meet each other at least once everyday. Tooru always visited early in the morning to interact with Iwaizumi only to see him again later on at night when he traveled with Yahaba.

Whenever he finished taking pictures underwater they would both just spend the rest of the day with each other's company, hugging, touching, petting. It all became natural for both of them, almost as if a reward of some sort. 

But at the end of the day Oikawa and Iwaizumi would bond more and enjoy being together, even if it was for an extra hour.

The mer wouldn't be able to hear him talk while underwater much to his disappointment, but being able to have alone time with the human in a more intimate way like holding Oikawa, was self satisfying.

This is how the days would go.

He'd wake up, have breakfast, relax and talk to Kuroo. While also having the time to text his other friends and Shigeru.

The younger man was incredibly nice and he found himself talking for hours through texts with Yahaba the same way he would with someone he knew for a longer time.

Tetsurou would always ask about the mysterious man Tooru was so interested in to have the need to put on makeup. Something he never did before. Oikawa would simply reply that they were still getting to know each other. It seemed to satisfy his curiosity for a while so that would be his go-to answer.

Iwaizumi had learned a lot. The mer picked up on queues incredibly fast and had learned how to nod and shake his head when answering. At first he would confuse them with each other but after two days he understood and caught on when to use each head movement.

Tooru was euphoric when he finally got the mer to nod when needed, always answering to Oikawa's yes and no questions that revolved around food.

Tooru has received the chance to get an in depth view on the mer's facial features whenever he would go scuba diving at night.

Iwaizumi carried nictitating membranes whenever he was underwater, only ever disappearing from view whenever he was above water. It was most likely used to blink away any sand or dirt that got in his field of vision without having the need to actually close his eyes.

It was incredible and Oikawa wondered what would happen to the membrane? Would it hide below his eyelids, it couldn't just evaporate out of thin air, right?

It was around five in the afternoon at the moment and Tooru was heading back to dock his boat and head home to prepare for his night shift. He hasn't visited the shop to get a refill on his tank since the last day he visited; not seeing the need to because he wasn't using it after all. Oikawa still kept the tank in case of an emergency.
