Hetalia and missing their S/o:
America: Is literally a wreck if they left for more then three to four days, text every minute, calls whenever they have the time to talk even if it’s a short while. He would mopes around all day. But once you had returned you would be trampled in hug bear hugs, lots of sweet kisses, cuddles, everything.
China: He would become extremely irritable, laying around more than usual. He would call or text quite often (though not as much as America would). Once you came home he would immediately cheer up and would treat you to a huge home cooked meal.
Romano: He would never admit he missed you at all even if he did terribly. He would be rather scilent as you were gone and everyone could immediately tell he felt lonely, even his S/o themselves as they spoke, as he was much more loving then usual He would be rather happy to see you when you returned, even wearing a huge grin on his face as he met with you at the airport.
Germany: He would try deprately to distract himself from the taught if you by doing various work task, but eventually he be caught up to with his taughts. He would call you everyday, moring and night, to make sure you were doing okay, that you were getting all of the sleep, food, and staying at least a little active during the trip, not wanting something to happen to you. When you came back he would be holding your favorite flowers, and give lots of hugs and kisses dispite how ark ward he may have felt.
Veniziano//N. Italy: like America he would be a wreck, crying and whinging more than usual, eating more pasta, and spending lots of time with Germany who was annoyed by the Italian who would start to cry hysterically anytime something remind him of you. When you returned count on a very, very long hug as he begged you to never leave again as well as a dinner outing.
