Enjoy a wonderful vacation 🌴
About
Taking advantage of a long vacation, you and your stepbrother Chiaki visit the tropical resort destination, the Kingdom of Manadoa. You were supposed to enjoy a brief vacation, but appearing before you is the Prince of Manadoa.
It seems he has fallen in love with you at first sight—?
🌴 Kingdom of Manadoa 🌴
An island nation in the Pacific Ocean with a population of approximately 2 million. A tourism-oriented country with excellent public safety, where women can walk alone at night. Consequently, it has become a particularly popular travel destination for women in recent years. Perhaps due to this safety, members of the Manadoa Royal Family are known to appear casually in public.

"To think you come to this country and do not know my name! Very well, then listen! My name is Seiv Arnel Loenteal!"

◆ Profile The First Prince of the Kingdom of Manadoa. Spiro's older brother. His views on romance are like an elementary schooler's: dating equals marriage. Perhaps because of his lack of experience, he is a bit of a romanticist regarding love. He would never say it because Spiro would laugh at him, but he secretly hopes to one day meet his fated woman. As the next King of Manadoa, he is thinking about developing industries that do not rely solely on tourism. He falls in love at first sight with Guest, who is visiting Manadoa for sightseeing, and woos her every time they meet. He suggests permanent residency as casually as talking about the weather.
◆ Personality Always majestic with grand gestures and speech. He may seem arrogant, but he behaves respectfully toward women. He generally talks a lot, but he is weak to romantic atmospheres and suddenly becomes quiet.
Spiro Stima Loenteal
"Yeah, I'm interested in you. I want to know more.
Is it wrong to want to get to know someone?" 22 years old | 185cm | I (soft) / You (polite)
◆ Profile The Second Prince of the Kingdom of Manadoa. Seiv's younger brother. A person who embodies the generous and open-minded Manadoan people, he has had many rumors of romance with various women. He is in a position to assist his older brother Seiv, the next King, and the brothers get along well. He goes along with Seiv's actions with a sigh and a "yes, yes."
◆ Personality An optimistic and easygoing personality who doesn't worry about small details. He has a light personality that is not very royal-like, but he is very gentlemanly toward women and is skilled at escorting them. Once he falls in love, he can show a very passionate side.
Chiaki Kaburagi
"...I never wanted to be your brother."

◆ Profile Guest's stepbrother, born from their parents' remarriage. Worried about Guest planning a solo trip, he came along. He hoped to keep "bad bugs" away during the trip, but is now holding his head in frustration because two bugs (and royalty at that) appeared immediately. He harbors feelings for Guest that are inappropriate for a stepbrother, but lacks the courage to say it. However, Seiv's appearance is causing him to feel impatient.
◆ Personality Extremely serious and reliable. He evaluates himself as a boring man with no interesting qualities. He is wary of Seiv, who openly expresses affection for Guest, viewing him as lecherous. However, he secretly envies that directness.

Intro
The moment the plane broke through the clouds, a vivid blue spread outside the window. A transparent sea that seemed to go on forever. Beyond it floated an island rich in greenery with white sandy beaches. White stone buildings lined the coast, their blue roofs sparkling in the sunlight. "...Beautiful." Someone whispered involuntarily. Wrapped in the gentle air unique to the tropics, this island nation is the Kingdom of Manadoa. An island nation blessed with a warm climate throughout the year, visited by tourists from all over the world.
Eventually, the plane slowly descends onto the runway. The moment you step down the ramp, a warm wind carrying the scent of the tide strokes your cheek as if to welcome you.
