You play as a local florist who is generally well liked by the cast and builds up a positive reputation off of helping people be truly happy in the face of an environment that not only fails at doing so, but is actively discouraging you from doing so in its place - in other words, you're everything Dr. Habit wants to be. No wonder he's jealous of you.
A flower-related name seems to be a pretty good indication that the character in question has some connection to Dr. Habit, no matter how minor - Flower Kid, KamalNote "Lotus" in Hindi Bora, even Putunia Mollar, etc. However, if you want to take it one step further, Dr. Habit's relationship with each of these characters could also be taken to be representative of his relationship with his upbringing and his past interests.
Flower Kid is set up as Habit's heroic Foil practically from day one and is just as likely to be his savior as well as his murderer, similar to how Habit's interest in flowers was one of the few things that made him actually happy, despite making him all the more susceptible to abuse and ostracization.
It's implied that Kamal and Habit were friends (or maybe even that Kamal was an Implied Love Interest, depending on how seriously you take that Steam card illustration) even when Habit's mental health began to take a turn for the worst - unfortunately, it got to the point where Kamal began avoiding Habit by retreating to the terrace after Habit berated him one too many times (for something he himself caused, to add insult to injury.) It's Played for Laughs, given that this is a generally lighthearted game, but it's not the first time Habit pushed away something he cared about to focus on a career that couldn't be more ill-suited for him.
Putunia sees Habit as her Arch-Nemesis, the Green Menace, but Habit himself only acknowledges her once, on his bulletin board - and it's to say that she "understands." Given what we already know about Habit, it's very plausible that either he genuinely sympathizes with her situation despite what he eventually plans to do to her, or she reminds him of the Cheerful Child he used to be and he can't resist projecting a bit of himself onto her.
Trencil's default sprite shows him chewing bubblegum - which at first, only looks like a design choice made to obscure his fangs so that the player wouldn't immediately pick up on him being a vampire. Once the player learns that he dislikes drinking blood, however, it easily provides an in-universe explanation: the gum could be a way of weaning himself off of any lingering blood-sucking tendencies he might have left, similar to how former smokers will often use gum to quell the need to have something in their mouth.
At first, it doesn't seem to make much sense for Kamal to relegate the duty of talking down Dr. Habit to Flower Kid, as Kamal was Habit's friend and coworker for a long time and undoubtedly knows him better. However, there are a few reasons why this makes sense to do:
In Real Life, trying to confront a close friend/lover about a mental health crisis can make things more complicated when both parties involved have a tendency to get hostile and bring up old issues, especially since Kamal's feelings about Habit are already quite messy, as he is putting both positive and negative memories they've shared into context. Perhaps it's better for Flower Kid to do it as an objective third party with none of the baggage that Kamal and Habit have between them, and Habit is likelier to listen to an unbiased source.
Habit also already insulted Kamal's teeth (which seem to be a sore spot for him) and Kamal was already reeling from his mistreatment and firing, and forcing him to relive that would be pretty cruel. If Kamal confronted him, its likely Habit would merely shut him down like before. Because Flower Kid is an Audience Surrogate and Dr. Habit doesn't know anything about them, it makes it much harder for Habit to poke at any insecurities they may have and likelier to listen.
Dr. Habit's bulletin board demonstrates that he has a soft spot for Putunia, as he writes "So strong. Little one understands. :-(" (with the implication that she, like Habit, comes from an abusive background). Habit's Insane Troll Logic philosophy predicates on how people who are sad have all of their teeth despite never using them to smile, and it's implied that this insecurity stems from his own father knocking out Habit's teeth in a moment of anger. Putunia, arguably, is the exact type of person Habit wants to "help" with his delusional mindset: she's a Cheerful Child from an abusive background who has a missing tooth.
Her name is even a reference to both aspects of Habit's character: Petunia is a type of flower, while Mollar is a type of tooth.
Fridge Horror
There are kids at the Habitat - which is, as stated in the game itself, a wellness retreat meant specifically for those who are depressed or otherwise unsatisfied with their lives. Millie's age is unknown, but she can't be much older than 11, and Putunia is 7. Not to mention that there doesn't seem to be any adults tagging along with them. All of this begs the question - what would cause an elementary school-aged child to feel as though they needed to go somewhere else to be happy again, and why wouldn't their parents get involved?
There's a full image of Dr. Habit's bulletin board from the final PSA◊ floating around the Internet. The photos on said board are acccompanied by notes that are, for the most part, only semi-coherent remarks relating to the characters in question (i.e. calling Jimothan a bad cook or expressing anger at Ronbo for opening his carnival against Habit's orders.) But the only thing Habit has to say about Putunia is, "So strong. Little one understands. :-(" Combine this with Putunia mentioning the fact that nobody yells at her as a perk of staying at the Habitat on the game's official website, and you'll start to get the impression that she doesn't have the most stable home life.
It's never stated how exactly Habit acquired enough teeth to give himself three rows in total before the Habitat. Was he sneaking teeth taken from patients' extractions and simply grew impatient with how little he got at a time despite having more than enough? Did he live up to the title of Depraved Dentist during his medical career and harvest them en masse? Did he perhaps turn to more sinister options to cover up his tracks? Even if the last one is a bit of a stretch, there's a good number of possible explanations, and none of them are comforting.
