Yeah, this artist has Koizumi as a pretty damn respectable (and completely straight) man. Koizumi marries Mikuru and is shown as her future husband, but still treats her sort of like an innocent child the whole time, even the adult version of Mikuru.
Meanwhile, Kyon just gets jealous, and Haruhi actively ships Koizumi/Asahina, partly because she likes seeing the romance, and partly because it gets rid of her major competition for Kyon's attention. Amusingly, Haruhi is perfectly fine keeping Yuki around, in spite of the fact that she still obviously likes Kyon, too.
All around, I'm with Haruhi on this (as with so many other things).
Being held by someone so fetching as yourself is quite the honorIn fact, I like being stroked by you ♡However...
Clinging this tightly might cause one to be uneasy that they could touch you in an awkward place...*squeeeeze*Asahina-sanThere isn't any place I wouldn't want you to touch me Koizumi-kun.*pet**pet**squeeze*The way she invites me, so naturally oblivious, is rather bothersome...Koizumi's ability to stay rational leveling upHeh
