If you're expecting romance, you'll either need to wait a long time or just give up altogether. I gave up a long time ago and I'm now enjoying the ride of this pure gold comedy with BL characteristics.
At this point, I don't even know if them being together might make this manga better because... I don't see them being lovey dovey? But if they do end up together, I'll also get greedy and want to ser them getting married (???)
Spoiler though, in volume 7 and 8 (currently in serialisation), they get friendlier and clingier with each other, to the point the two guys pinning for them (Reo and Yokoshima) are constantly in the slumps about it, but Yokoshima in particular is hilarious in volume 7.
You can buy it here https://www.cmoa.jp/title/186720/
Just make an account and it is easy to buy thru PayPal. One volume cost me about $5 dollars. I can't read Japanese but seeing spoilers def makes me look forward to the translation ヾ(☆▽☆)
I recommend Renta better than Cmoa. I have accounts in both, and they both have series they release earlier than in the other portal, but with Renta you can get daily points for just checking in, points if you sign up for their newsletter, for writing reviews of what you buy etc etc. You can then exchange those points for buying or renting manga.

From being grossly homophobic, to fucking a guy, to liking a guy, kissing a guy, sucking a dick, eating ass and now swallowing cum.
That's what I call "character development" right here, ladies and gentlemen (and everyone else).
