Diamond head won't close down

Kaito and Hiromi turned back to Diamond Head and try to lure some friends as guests to the minshuku.
However the owner still insists on closing and going to Tokyo with Makoto, whose mother wants her back.
The girlfriends of the 2 guys come over to have a lil break and while they have some nice beach parties the owner leaves the decision of closing down to Makoto, because SIMPLE IS THE BEST....
