I appreciate the enthusiasm 😅😭. I fear I'm too weak to write slow burn. I just want them to kiss already fjfgskdhdkg. There would need to be some communication errors.

I think Jisung wouldn’t bring up that he was told it was a date. He would yell at his friends for it (maybe it's Felix and Hyunjin who know Minho from a dance crew/club). And they would insist they did it for his best interest and that him and Minho would be perfect together. Jisung almost wants to spite them now by being super platonic with Minho. He's very embarrassed at first for how he'd flirted with him, so he tries to overcorrect and act very bro.

Minho would be a very courteous roommate. He pays rent on time. Keeps clean and quiet. He has a solid routine. He gets up early and goes for a run meanwhile Jisung is the type to sleep in. Sometimes he'll be getting up as Minho returns. He'll see him all sweaty in his running clothes and have to hide before he can embarrass himself again. He'll grunt sleepily like, "morning," and then run to the bathroom.

Minho doesn’t speak to him much at first. He asks permission to put his stationary bike in the living room. Jisung say, "of course, it's your space too now." Minho asks, "were you about to cook?" Every time he wants to use the kitchen even though there is no evidence that Jisung has ever used the kitchen.

Minho is very hard to read. I think it should be from Jisung’s pov so we don't know what Minho is thinking this whole time. Jisung is trying so hard to not have a crush on his roommate, but it's hard. When they first met he viewed him as a potential romantic partner, he can't just turn that part of his brain off. He yearns. My version would have to have some time skips to prolong the burn. They slowly become 'friends'. They bond over shows and documentaries. When Jisung is watching something on the TV Minho starts staying to watch too and makes comments.

Jisung's feelings grow as he realizes how much they have in common and how easy it is to be around Minho.

I don't know who should finally confess, or if it's a forced reveal, but I think it would be revealed that Minho liked Jisung the whole time. Maybe he even likes him too much. He was also burying his feelings because he really needed a new place to live and he didn't want to ruin it by coming onto his roommate. He was afraid that things would become awkward if he was rejected.

Anyway they are silly, but once the feelings are out in the open it's great. They start calling their evening hangouts 'dates' and Minho probably starts cooking for Jisung to show his love, he's very acts of service. And Jisung is so smitten and happy to finally have a boyfriend. His friends try to gloat that they were right and he can't even be mad a them anymore. They were sort of right after all :D
