Jeongwadate S2 seems to be a complete spin-off since its new episode numbering is going S2 Ep 1, etc. The first season of Jeongwadate episode numbering was within the Changing Majors episode count (Ep 113, etc). It might be better to have a new page dedicated to Jeongwadate similar to the first season's winter vacation spin-off. The Animal Science ep was technically the last ep of the semester, but waiting for the new semester in September to readjust the ep numbers if it is wrong!
