Going on a Date
Once Relation is at least +10, you can take the girl of your choice out on a date. You will always start at the Tavern. There are several options to start: They will also start with two stats: Fun and Lust. How much these bars start with depends on their Relation and Lewdity.
 * 1) Talk
 * 2) Activities
 * 3) Relax
 * 4) Ask Needs
 * 5) Change Location

At high enough Lust, their Lewdity will temporarily increase by 1.

Some activities will cause temporary buffs to Lust gain or Fun gain.

1) Talk
Each girl has several different topics to discuss, including their job, their history, what they think of you, and what they think of the location. These generally cause no change, or slightly negative, depending on the topic, and serve more of a purpose for you to get to know the girl to make better decisions on where to go next and what to answer to pick when given a choice.

2) Activities
Each location has several different Activites to choose from, as well as count as a public or private location.
 * Tavern (Public)
 * Drink (will refuse if too full)
 * Juice (-4 Gold, has a chance to cause an Aphrodisiac effect)
 * Alcohol (-10 Gold)
 * Milk (-100 Gold)
 * Eat (will refuse if too full)
 * Snacks (-10 Gold)
 * Basic (-20 Gold)
 * Luxury (-50 Gold)
 * Beach (Public)
 * Explore (Land)
 * Swim
 * Fish (takes 15 minutes)
 * Cook
 * Preserve (+1 Food)
 * Buy Food
 * Algae (-10 Gold)
 * Fish (-20 Gold)
 * Sweets/snack (-20 Gold)
 * Forest (Private)
 * Camp (Takes 30 minutes)
 * Hunt (Takes 15 minutes)
 * Explore
 * Home (Private)
 * Cook (Takes 15 minutes)
 * Cook alone
 * Cook together
 * Swim (pool) (Requires pool upgrade)
 * Relax (sauna) (Requires sauna upgrade)

3) Relax (Takes 15 minutes)
Slightly increases or decreases Fun, depending on the girl's mood. Reduces Exhaustion (-2 I believe). Good to use when arriving at a new location to avoid changing locations too quickly and getting the "we barely just got there" penalty. Also good for decreasing how full a girl is, in order to buy her more food.

This options also allows for random events to occur, especially in the Tavern.

4) Ask Needs
Ask the girl if she needs anything (sex, change location, food, something exciting). Depending on the girl, she may refuse to answer you clearly. Small negative effect on Fun.

Having Sex
When a girl's Relation is increased to 30+, you gain a new action: Action/Sexual

Each girl has a different set of actions. See their respective Dating Strategy pages to find out more.

In general, each action requires a certain amount of Lewdity, which is a separate stat like Relation. The frame of the picture shows pink petals equal to the amount of Lewdity the girl has (Or you can look at the number in the very bottom left).

In order to increase Lewdity, you have to successfully pull off a Sexual Action that is thrilling for the girl. In order to do that, raise her Lust percent until it's near full (80% or higher), and you'll see that the Lewdity number now shows a temporary yellow +1. That means the girl is willing to do slightly lewder actions than normal.

Each girl's willingness to preform sexual actions is different. But as a general example, if she is at lewdity zero, try increasing her lust to 80% or higher, until you see the yellow +1 in the bottom left. Then, in Actions/Sexual (you must have 30+ Relation with her to see this option), request for her to flash her tits in a private location (Such as your Home or the Forest). If successful, her Lust should drop, her Lewdity should increase permanently, and her picture should change. If not successful, either she will preform the action and Lewdity won't increase, which means it was not thrilling enough for her, or she will refuse your request and be embarrassed, which means you need to try something less thrilling.

You can only increase a girl's lewdity twice per date. Sometimes the game will remind you, sometimes it won't, so it's best to keep a note of it and end the date after the second increase.

Recruiting the NPC
When you finish a date, you will receive a large amount of Relation, depending on how well you did (or lose some if the date was terrible). Once you gain enough Relation (60+ (?)) it will say that she Loves You under her name at their normal locations, and you can Request for them to join your party.

Note: You are still given the option to date them even after recruiting them, by click on them in your party and selecting the option to date.
