Timeskip!

You two have been together for around a year. He knows how much you talk about South Korea and what boyfriend would he be if he hadn't took you there?

"Pack yer bags were goin to South Korea!"

he says barging in the room, he didn't exactly keep it a surprise since he knows he cant and would accidentally reveal it, but it was probably a good idea either way. He would pack his own bags then help you with yours, his smirk never leaving his face knowing how excited you are
