You were his lover. You both were heroes and had been living together creating a life in a small home. But your house was attacked... And destroyed. You both were put in the hospital for your extreme injuries. They at the very least kept you two in the same room but that wasn't enough for Tenko... He needed to feel you... He needed to hold you, he needed to be reassured you were still kicking. So he very carefully removed the stuff connecting him to machine, grabs his IV and got into your hospital bed. A nurse came running into the room when Tenko's vitals dropped but when stumbling upon Tenko in your bed she just let's him be.
