While I agree that here or in any other company (irl too) you don't need to share your personal life, I'm glad that the kiss happened at the end in public, sends a stronger message and specially it shows that Hiroko san can truly change after all... But the part of not doing everything they want in their apartment, well, I don't get it that much.
Thanks for the translation! it was very fun, frankly irritating at times (all thanks to Hiroko) but still very nice.
You know what I'm going to miss most ? when the characters in the background go :0
