Tsuruda is a pain in the ass. I relly hope either lucha or mikkun is gonna be harsh on him and tell him that they are happy together and that it's none of his business. Because we can all see that miwa and Saeko really work in order to perfect their relationship.
Tsuruda is just a stupid jealous little fart who can't get over the fact that a girl he likes doesn't like him back. I would like them to share a passionate kiss right in front of him JUST to upset him.
