Thanks for the chapter!
Why is title "I Shaved. Then I Brought a High School Girl Home."? I haven't seen him shave once. If instead of "I Shaved." it was "I was Heartbroken and Got Drunk." or "I Got Drunk." it'd fit. Also, don't think LN ever mentioned him shaving in the first couple chapters either, just went on a date, turned down, got drunk, met and took Sayu home.
Wonder if Gotou really has a boyfriend or if that's a shield she uses to keep from getting too close to someone due to a few bad experiences. After all, MC probably not the only one who's tried asking her out considering her ability and looks. Be interesting to see if MC gets into a relationship with her again although if does probably won't be until ch50-100 assuming they don't just stay co-workers.
Hope he helps Sayu learn to value herself more and maybe find a way to support herself or get money other than prostitution. At least to me, sex should be mutual pleasure between two adults not one getting rocks off at other's expense. Also, even if an upscale brothel makes sure it's workers have clean clothes, healthy food, and checkups with a doctor, it can't do the same for it's clientele who could infect the women with a variety of STDs they caught from a bad choice in partner. In any case should have her do some workbooks to raise her knowledge at least enough to pass a highschool equivalency test so can have more options getting a job and getting a stable income.
