The One-Eyes cling and follow their hosts, leaking worries and fears, but Jun refuses to interfere and even though Haruka wants to help, he is always talked out of it by Jun. Why are they the only ones able to see the One-Eyes?

From MangaHelpers:

This volume contains four short stories by Ine Arinaga. In the first story, two friends can see strange creatures every Thursday. These creatures climb onto people, stating their troubles in simple terms. Though they worry about the people around them, there is little they can do to help. Other stories involve situations including a girl who wishes away a boy's face and a box that contains what the person who owns it truly wants. [tethysdust]
