Evidently not a very good teacher if she's making students write sentence FRAGMENTS on the board. You have a subject, make them write the damn predicate!
@lukkas Pay attention to what tags mean. This is not what the hot tag is for, and it should be incredibly obvious that multiple_girls and short_hair don't apply here either.
Also, what evidence do you have that this was drawn by ecchi_pantsu? It falls far short of his usual level of workmanship, and that's not his signature either. You need to provide a proper source to prove the artist was who you say it is.
