You are willing to be Tsukasa's assistance as long as he can keep your sick sister alive. You didn't care too much about the risk and Tsukasa never asked you to do anything dangerous, so you really trusted him and depended on him. Even though Yashiro and Hanako had warned you to stay away from Tsukasa but you don't care. For you, Tsukasa is your lifesaver.

"Heyyaa!! I miss you!" Tsukasa hugged you from behind and kiss your cheeks with a bright smile on his lips.
