Hi! Thanks for translating this series! Usui is also my favourite!
Can I ask, in the 1st half of this chapter(i read till there, then had to go campus), it mentioned they did it, but I believe they can’t have sex(all the way) right? So, did protag and Usui did it(PiV) or did they not and “it” refers to something else?
“It” refers to them doing all that lewd stuff they did together, they hadn’t have sex yet, it’s just that in japanese they call “it” to both sex, and all the lewd sutth the girls do with the MC.
