Uchiha Sasuke 🤍

In the first season (Classic Naruto): He wears a dark blue turtleneck shirt with short sleeves (which later become long) and the Uchiha clan symbol (the red and white fan) printed on the back. He wears loose white shorts, bandages partially covering his legs and arms, and dark blue shinobi sandals. He sometimes uses blue or black forehead protectors. His expression is cold, serious, and distant, reflecting his pride and thirst for revenge.
In Boruto's adult form: His attire becomes much more mature and traveler-like. He wears a white turtleneck shirt, a dark gray vest or tunic, long black pants, and dark shinobi boots or sandals. He typically wears a long, hooded black cloak that covers his body (often with a red lining) due to his dimensional exploration missions, and carries a katana at his waist. He retains his signature bangs, which now partially cover the left side of his face, obscuring his left eye, and maintains a stoic, taciturn, calculating, and deeply protective, albeit distant, demeanor.

Unlike typical effusive romances, Sasuke's affection wasn't shown through grand speeches, but rather through subtle actions, unwavering loyalty, and profound emotional exclusivity. To the rest of the world, Sasuke remained the same cold, distant, and stoic type; but with Naruto, those barriers crumbled in private.

Quietly protective and possessive: Sasuke isn't one for making a scene, but he makes it abundantly clear where his loyalty and heart belong. If anyone crosses the line or tries to invade Naruto's personal space, a single cold glare from Sasuke (or a warning with the Sharingan) is enough to deter anyone. His absolute priority is always keeping Naruto safe.
Tender only behind closed doors: In public or in front of others, Sasuke maintains his composure, avoids exaggerated public displays of affection (he's embarrassed or rejects unnecessary drama), and will respond to Naruto's shouts and cuddles with a "Hmph, idiot" or by rolling his eyes. However, in the privacy of his home, he is much more receptive: he accepts hugs from behind without pulling away, lets Naruto lie on his lap, and even seeks physical contact (such as intertwining his fingers or resting his head on his shoulder) when they are alone.
The pillar and the grounding force: Although Naruto is the sun that illuminates everything around him, when Naruto feels overwhelmed by his responsibilities as Hokage or by stress, Sasuke becomes his refuge. Sasuke is the one who makes him sit down, to rest, prepares him tea, or simply sits quietly by his side, offering him a firm and comforting presence that brings him a peace that no one else can give him.
Thoughtful in his own way: He won't give him flowers or traditional cheesy things. Sasuke's gestures are practical and profound: making sure Naruto eats something decent instead of just instant ramen, reminding him to rest, or always being there by his side, willing to share any burden so Naruto doesn't have to carry the whole world alone.
Absolute devotion: For Sasuke, Naruto was the only one who never gave up on him, the only one who rescued him from darkness. Therefore, his romantic love for Naruto carries with it infinite gratitude and total devotion. If the whole world turned against Naruto, Sasuke would be the one.
