Zenyuki

Zenyuki is the het ship between Shirayuki and Zen Wistaria from the Snow White With The Red Hair fandom.

Canon
Shirayuki is introduced as a young, hardworking herbalist in her own shop in the country of Tanbarun, however, she ends up attracting more attention for her hair which is a rare bright red. The first prince of Tanbarun, Prince Raji Shenazard, hears the word about her being the most beautiful girl and sends his messenger to her shop, who informs Shirayuki the prince wants her to be his concubine. Without any other choice, she mixes a bunch of medicine for her customers and cuts her long hair, leaving it as a parting gift, and leaves Tanbarun.

After being dropped off, Shirayuki falls asleep outside a stone house in the forest. The next morning, she sees a white-haired boy run up the wall before tripping and falling at the sight of her. At first, he doesn't trust her when she tries to heal the injury to his arm but proves herself when she uses it on her arm instead, by hitting it against his sword. He introduces himself as Zen and the two start on more friendly terms. Zen introduces her to his friends, Mitsuhide and Kiki.

After Shirayuki explains her profession, Zen asks why she would leave home with her talent and Shirayuki somberly tells him it's not important, before letting herself outside. He decides to go with her, not wanting to leave her alone by herself. Shirayuki talks about how comfortable she had become in the forests and mountains while studying to be an herbalist until a strand of her hair gets caught on a splinter of a tree. She asks Zen if he could cut it for her, to which he says he will if she answers if her cutting her hair had something to do with her running away. Shirayuki remarks that he's a terrible person, and he smiles and shrugs.

Zen responds with shock when she reveals she had run away from a "famous boy" who wanted her as his concubine because of her hair, seeing that if she obeyed it would be like he was buying her off like an apple at the market. Shirayuki remarks she did give him partially what he wanted and left her hair behind, which causes Zen to burst in laughter and calls her idea ingenious. He then compliments her for getting away, saying it's her lucky red after all. She asks him what he means and he tells her, "Color has meaning. And red is supposed to represent fate. You may not like it much now, but your red might lead to something good when you least expect it."

In amazement, Shirayuki tells him he has an amazing outlook and he teases her about getting her respect. Mitsuhide and Kiki watch them from afar in the forest, Kiki mentioning that Zen has taken a shine to her. The two head back but Zen notices a basket on the front step, then Shirayuki realizes the hair ribbon she left is tied to the basket.

Zen reads the note from the basket of apples, finally seeing Shirayuki is from Tanbarun and mentions that someone must've traveled all the way to the border to find her. He then asks how bad was it that she had to flee the kingdom, to which she tells him it's because of who it is and tells him it's the first prince. Zen slams his injured hand in frustration recognizing whom she's talking about, before settling down and mentioning that Raji has had people tearing up the border crossing roads, saying that he will expect that something he wants already belongs to him.

Shirayuki picks an apple from the basket, her thumb brushing over the bruise on it and sadly murmuring it's red is no good anymore. She then says she was kidding until Zen walks up to her, taking a bite from the apple much to her surprise. Mitsuhide lightly scolds Zen for eating her apple, which Zen tells him to stay out of it. Shirayuki apologizes and Zen warns her to put the apple down, before collapsing to the floor. Shirayuki realizes the apple was poisoned and rushes to her bag to help him, worried she doesn't have an antidote until the same messenger from Tanbarun walks in and sees Shirayuki didn't eat the apple. He then tells her there is a cure but will only be given if she comes with him quietly.

Shirayuki finally confronts Raji, who talks more about his image being tainted when she ran away rather than curing Zen from the poison. She begs him to give the antidote and he says he will, if she agrees to be his concubine or if she'd rather have him send another apple. Remembering the words Zen said to her, Shirayuki decides to let Raji take her as his concubine only if he knows what he's getting. Suddenly, the door bursts open, and Zen objects to this, revealing Raji's guards defeated by him and Mitushide, and Kiki. Shirayuki runs to him, asking if he's alright and he mentions that he's grown a poison immunity over the years, just in case.

Raji reveals he intended for Shirayuki to bite the apple and to be taken back to Tanbarun while in her immobilized state, Zen remarks he wasn't surprised he'd be the one behind a bad apple. He gets the panicked prince to swear he won't come near Shirayuki again and gives the antidote, before being taken back home by carriage. After Zen is cured, Shirayuki apologizes as she feels responsible for him being poisoned. He reassures her before lending his hand out for her to take, wanting her to come to Clarines. In the narration, Shirayuki mentions this as her path to destiny.
