Would have been glad with just sol content. This arc is undoing most of the character growth they' ve accomplished. He is your boyfriend, just talk to each other- heck don't we share all kinds of gossips/events with our besties knowing we're in a safe space with people who knows how we track?
Author did not need to add this guy as a love interest for either mcs. Miss secretary S. She deserved a hot dude for all she did/put up with- author could have thrown Doeyeon her way.
