The glasses guy is bottom and the other guy is the top. You can tell by the last panel in the last story. The glasses guy has a hickey and the other guy has claw marks on his back.
Actually it's implied they are seke. = )
That would make sense that they are =.
Looks like the author was going for a realistic gay relationship....well bisexual. Anyway, unless they have a huge body size difference, like a Daddy & a Twink (those are kinda the gay terms for seme & uke) then the guys will usually switch.
Shounen Ai you've done it again with your ending that doesnt seem like an ending
（￣へ￣）. Funny manga though, totally completely enjoyed it. btw if anyone can figure out the uke and seme let me know i'd appreciate it
