After marriage, Do-gi doesn’t suddenly become “peaceful,” because his life with Rainbow Taxi is still dangerous—but he does become more intentional with coming back home. No matter how late it is, he always checks in with you, even if it’s just a short message like: “I’m alive. Don’t wait up too long.” It’s his way of saying “I’m coming back to you.”
He struggles at first with the idea of marriage itself. Not because he doesn’t love you, but because he fears attachment after everything he’s lost. So when he finally calls you “wife,” it sounds almost unfamiliar on his tongue—like he’s testing whether he’s allowed to have something stable in his life.
Living with him means learning his silence. Do-gi isn’t overly expressive, but his love shows in small, constant actions: he fixes things around the house without being asked, quietly checks all the locks before bed, and instinctively stands between you and danger without thinking twice. Protection is his love language, even when the world is calm.
He still carries his trauma heavily. Some nights he wakes up disoriented, breath sharp, body ready for a fight that isn’t there. On those nights, he doesn’t always talk—but he will reach for you. Not to wake you, just to feel you there. Your presence is his grounding point.
Emotionally, he’s slow to open up about his missions. Even after marriage, there are parts of his work he keeps locked away because he doesn’t want you carrying that darkness. But over time, if you’re patient, he starts letting you in—not the violence, but the burden behind it. You become one of the only people he allows to see him tired.
Despite everything, he’s surprisingly soft in private moments. When he’s truly at ease, he leans into quiet domestic routines: sitting with you while you eat, wordlessly sharing tea, letting his guard drop just enough that his shoulders relax completely. He might not say “I love you” often, but he shows it by staying close.
Arguments are rare, but when they happen, they’re never loud. Do-gi doesn’t raise his voice easily—he goes quiet instead, withdrawing into himself. The real challenge is pulling him back out of that silence with patience instead of pressure.
And when it comes to loyalty? It’s absolute. Once he chooses you, there’s no hesitation. Even in the worst chaos of his world, you are not something he risks or negotiates with. You are the one thing he fights to return to, not for revenge, but for life.
