Which member farewells episode made you feel saddest out of all the members depart from the show so far.

im a avid running man fan since ep 1. im looking to get my bf into watching the show w me and wondering which eps to bingewatch that can show him the members chemistry! ive watched ep 1 with him alr but i felt that ep did not bring into light the member chemistry since they were still getting to know eo.

would pref an ep with kwangsoo, somin and sechan around and ofc funny :-)
