Those who are wishing for season 3, it seems that you have to wait further. It was announced that Baby Steps is going to have a live action adaptation, as mentioned in the 27th issue of Weekly Shounen Magazine (where Baby Steps manga is currently serialized).
As such, whether we can put details about it or not ... let's see. Probably the cast? But for now, just hope that there will be raws available.
