hello whoever left this i am giving you a big messy smooch. OKAY SO chan is 1000% the one who proposes. Kim "Oblivious To Romantic Advances" Seungmin got a boyfriend and stayed perfectly happy there. chan sweats and second-guesses every possible opportunity to propose. a day6 concert and a lotte giants baseball game are both considered, but discarded (too public, and seungmin would be WAY too distracted/invested by the event itself). he wants it to be significant, though, so if it can't be the setting, he can make it the day—a certain number of days since they first met, since their first kiss, since their first proper date… chan SPIRALS about this for SO LONG. he starts carrying the ring box in his bag Just In Case. and maybe one day he grabs the thing directly next to it and as he pulls the other thing out, the ring box clatters to the floor… and seungmin scoops it up without thinking. chan blurts, "open it," and seungmin blinks at him. chan scrambles to kneel down, babbles, "waitwaitwait, hang on, gimme that please, this is—" and seungmin's already opening it by the time chan's hands are curling around the box. and chan whispers, "will you marry me?" and he's on the verge of tears. and now SEUNGMIN'S on the verge of tears. and seungmin tells him he's an idiot and to ask him again later and chan asks if he'll say yes and seungmin smacks his shoulder and kisses him and it's the saltiest kiss either of them have done and they're in love the end
