Exactly!
Everyone except for Tomoe, not that he hates Kokutou.
Lio is clinging on to Shiki in this pic but the creator Kinoko Nasu
commented that he is subconsciously transgender and is actually attracted to
"male Shiki" and Kokutou. I personally think Tomoe have probably liked
Kokutou (as a friend/mentor) if only they met before Shiki did.
