Like a Dragon: Infinite Wealth - 27 - Substory 23: The More, the Plumeria
To start this substory, you first need to find two trees in the city, one at Sunset Park, and one at Harbor Park. After that I make a little detour to grab the reward for 100 friends, the mighty Dragon Boots!
After that, it's time to go to Waikiki Street where you'll find a young man and woman arguing about something before running off. Follow the woman to the little park at the east and she'll explain the situation. Her friend Yuri is sad because the woman he likes, Jessie, is leaving Hawaii soon, and she wants him to give the lady a lei of blue plumerias as a gift to hopefully help them keep in touch.
Ichiban, moved by the tale, decides to help Aina by guiding her to the trees he has spotted, starting with the one in Harbor Park... that is currently in danger because of two Sumo wrestlers putting on a show nearby! Nothing to do but convince them to stop... by force! They're at level 17 and can take a good beating, but aren't too threatening.
After that you'll split up with Aina and have to go to the tree in Sunset Park, she'll then call to meet up at the Art Walls, a pretty dangerous area, so mind your step. We can see Sawai and Kiana there though, which is nice!
Once we talk to Kiana, she can finally make that lei, and she'll ask Ichiban if all men like older women, giving you a Personality Chance, I answered that "Age isn't everything." and got a boost in Kindness for it.
You'll then go to Yuri and encourage him to go see Jessie, where events will take an unexpected turn, but with a very sweet ending. I didn't plan for this video to be published on Valentine's Day, but it sure is fitting!
Your reward will be a Pareo of Happiness, an accessory that has the wearer recover HP when a buff is applied, which has great synergy with the Dragon Boots I got too!
