Only the ring finger knows

Author: Satoru Kanagi, Hotaru Odagiri.
Genre : Shounen ai, Shoujou, School life (No smutty act in this manga ^^)
Length: 1 volume

I think this is shounen ai manga with shoujou plot. It's about pairing ring. Couple always wear a pairing ring. But, Wataru Fujii wearing a ring although he is still single. But someday he accidentally switches the ring with his popular and handsome senior, Yuichi Kazuki. Finally they know that their rings pair up. It has same design although the diameter is not same.

Although this manga is not smutty, the story is sweet and not too dramatic. There are novel version of this manga but i'm not yet read it.

I like Yuichi Kazuki. He always harsh to Wataru since he met face to face at the toilet and switches ring. But actually he is in love with Wataru. I guess he is Tsundere type :D

*Although he said that "It's creepy being paired up with a guy", actually he's glad ^___^ *
