My Wife is a Little Intimidating, Volume 2 (My Wife is a Little Intimidating #9-16)

After putting off their honeymoon for work, Kosuke finally gets around (after being shamed by his colleagues) to a relaxing getaway with his wife... but he botches it big-time. And though they make the best of it and put a spark back into their relationship, that newlywed feeling is short-lived by fears that his wife is cheating, not to mention her grumpy father suddenly coming to town.
