I don't think so, though I think Matthew would have some top scenes, Jin is pretty clear he wants a submissive, and knowing the type of person Jin is he won't settle or change anything else, also though Jin isn't as widely build as Matthew he has a more top personality as well as not getting shy during the sex scenes, however Matthew does
I mean it’s easy to tell Jin is gonna be the bottom it doesn’t seem right for Matthew to be the bottom when he looks more like a seme and also acts like a seme. From reading it and seeing how they act I think jin will be the uke, because it’s just leading up to him being the uke. He might just be a more leading stronger uke. I’ve read many manhwas/mangas that are like that some ukes are just a leader in the relationship/during se)x (as in they arent shy. And they are more of the badass) > but they aren’t always the seme, i mean you can honestly tell Jin is gonna be the uke (it would be cooler with them switching)
I hate stereotypes though. I love a big uke and it's not realistic to real life relationships when if you want to bottom, you bottom! Just because you look a certain way doesn't mean these stereotypes should be pushed upon you. I've been so disappointed in the past when I can totally see the shorter one top but noooooo you have to be taller to top. Some authors have no originality when it comes to tops and bottoms. Also Jin gives major dom vibes but I also think he will unfortunately bottom in this. It's rare you see verse couples in yaoi/BL manga. :(
There is many mangas that I’ve found that have an seme that is shorter. You just haven’t been looking :) comon now ! Don’t be to blown away this is just a manga that is different then what u are looking for.! I have seen some manga’s where the seme had a younger look was shorter and was much skinny and turns out they where the SEME I was pretty amazed I would totally give you the name but i forgot it.. Anyways i wanted them to be a switch but clearly Jin is the bottom and Matthew is the top. I still see Jin as somebody who can top but I mean with Matthew gonna be his partner it’s SO CLEAR THAT HE ISNT GONNA BE A TOP (maybe) BUT HE MIGHT BE A BADASS AND LEADING BOTTOM SO THATS STILL A WIN WIN FOR ME
Omg nooo I definitely found so many ones where the seme is shorter but that's not the point, I totally think Jin could top but I just get the vibes that's because Mathew is taller he will top because he seems quite submissive. We'll see but yeah unfortunately it seems Jin in gonna be a dom bottom.
Also I don't mind a short uke but I love with they are adamant, if that makes sense. Not rapey but act in denial and secretly ike it. I'm a little picky lol.

When will they have a proper sex omfg I want to know who will be the top already
