Why did MARUTA name two of their work Utsusemi Zenpen (https://e-hentai.org/g/541498/404a239c47/)? Zenpen literally means "first half", so shouldn't there only be one "first half"?

This would be so hot to do in real life, would love to be the girlieboi. My only problem with this manga is that it rushes to quickly revealing that one of the twins is a boy. It would have been hotter if they teased the librarian a little more maybe had her lift the girlieboi's skirt and reveal the bulging panties first then make her take his panties down and pull out his sissy dick. Oh well, cant have it all...giggles!!

I wonder if you can tell the chronological order of these shorts based on the uniforms they wear each time they switch schools...

Actually 編 (hen) means "part".

前編 (Zenpen) - First Part (prequel, former), always being the first
中編 (Chuuhen) - Middle Part
後編 (Kouhen) - Last Part (sequel, latter), always being the last

There really are no numbers. And there are translation ambiguity issues with those "hen"/"pen" stuff, so just call them as is: "Zenpen", "Kouhen", etc.

Unlike その１ which is "Part 1" and １話 which is "Story 1".

And yes, why the hell are there two "Utsusemi Zenpen"s? So there will obviously be two "Utsusemi Kouhen"s too?
https://e-hentai.org/g/541943/0c30616f07 is the Kouhen of which story?

The reason is that https://e-hentai.org/g/589667/aa777aca1c is Chapter 7 of "Hatsukoi Tribute" (https://e-hentai.org/g/643258/63f1190407/) and https://e-hentai.org/g/541498/404a239c47 is Chapter 8 of "Kanojo Zokusei" (https://e-hentai.org/g/595814/6509a62182/). Both storylines share the same characters (and titles) but appear in different tankoubons!
