I'm a fan of JaFirst and I mostly enjoyed this drama.

However, I have to say as a Japanese, that the onsen (Japanese hot spring) is not a place to make love, especially from a hygienic standpoint. Sometimes the water is circulated.
And also, there was a scene Ashi and Title went together in a small onsen, but the situation never happens in reality. Small onsens are for families or lovers, not for friends.

Another point is, Mr. Tanada was really weird and looked like a swindler or something rather than a film director. I want to ask writers why they made him like that.
