The "Shinobu" you're asking about determines who she marries: Shinobu Kawajiri from JoJo's Bizarre Adventure marries Kosaku Kawajiri (though later confused with Yoshikage Kira), while Shinobu Kocho from Demon Slayer doesn't marry anyone in the canon but has strong fan pairings, most notably with Giyu Tomioka. If you mean the Urusei Yatsura character, Shinobu Arai's future partner changes, but she's often linked with Ataru Moroboshi or Shutaro Mendo in fan dreams/scenarios.
In Diamond is Unbreakable, Shinobu Kawajiri is married to Kosaku Kawajiri. Her marriage is strained and passionless, leading to resentment. Her feelings shift when Yoshikage Kira, disguised as Kosaku, treats her kindly, sparking unexpected affection from her, unaware of his true identity.
First, Takahashi tried to shift Shinobu's romantic interest to Mendou. It worked because it created lots of hilarious moments in the series, but later, towards the end of the manga, Takahashi once again decided to change things up and came up with Inaba as the definitive romantic partner for Shinobu.
So yes, Araragi and Shinobu are in a romantic relationship, although its nature is slightly different than how we humans interpret it.
There is no clear evidence of a romantic relationship between them. Giyu's relationship with Shinobu appears to be strictly professional and platonic.
Shinobu Takatsuki (高槻 忍, Takatsuki Shinobu) is a gay character from Junjou Romantica.
Giyuu Tomioka
Two words: Concupiscent and moderately-paced. He starts with a kiss on your cheeks until it reaches your luscious lips, and trust me, this guy does not hold back, he doesn't like disingenuousness and which is why he'd always be giving 100 percent.
Inside of Limbo, Doma, having heard and been touched by Shinobu's strong faith and belief in her comrades and fellow Demon Slayers' ability to defeat the demons and slay Muzan, seemingly begins to develop genuine feelings of romantic attraction towards her.
Both Obanai and Sanemi have poor social skills, so they mistook Giyu's highly introverted behavior as arrogance, which made them dislike him.
While Shinobu still holds a deep hatred for Demons as a whole, it doesn't seem to extend to Nezuko, partially because she sympathizes with Tanjiro and his kind nature being similar to her sister's.
Her kisses can range from tender sweet kisses to passionate make out sessions. If you are around others don't expect kisses on the lips from her. Shinobu is not that big on PDA so she opts for cheek kisses instead.

During his confrontation with the Stand Stray Cat, Kira expressed a desire to protect his "wife", Shinobu Kawajiri, and even showed relief at her safety.
While many Hashira died in the fight, some survived: Giyu Tomioka, the Water Hashira, and Sanemi Shinazugawa, the Wind Hashira, both survive the final fight, carrying on the memory of their fallen comrades. Tanjiro also survives, and after the war, the Demon Slayer Corps disbands because demons are gone for good.
Despite her hateful responses towards his comments, Doma comes to an unexpected realization by calling Shinobu cute and claiming that even though he "doesn't have a heart anymore, [he] feels like it's beating" when he looks at her.
Sanemi and Obanai rank low as their actions and abrasive personalities make them less likable.
In the Demon Slayer manga, it's explained that a pervy uniform maker designed that version for all female slayers, but most of them refused to wear it. Shinobu even burned hers, while Mitsuri had no idea everyone else rejected the design, which is why her outfit stands out so much.
Giving Him Physical Clues
