YMMV / Full Service

• Fanon: Thanks to four of the love interests appearing in the crossover "Gyee" video game, it is practically Canon among the fandom that Kovit, Okan, Oki, and Rald are all huge "Pokémon" fans with the possibility of the rest of the cast, including all of the male background characters, also being fans as well. In addition, thanks to gift preferences and the two-headed dragon gift, Kovit, Oki, and Rald are commonly depicted choosing Charmander as their generation 1 starter while Okan chooses Bulbasaur. Finally, it is common to depict that when Okan and Oki were kids that they would link their games with Game Link Cable to trade and battle, with Oki always winning due to the type advantage of his starters in addition actually strategizing while Okan usually just thinks with his heart or soul.
• One True Threesome: You can score a threesome ending with the twins, provided that you raise their relationship point and go on dates with both of them. There is also a "threesome" reward containing CGs showing combinations of the four main love interests, but according to Mazjojo, these are non-canonical to the main story.
