   Summary

   Tsukasa love bombs and grooms Rui while he was lonely and depressed and for once Rui feels happy and loved by someone. Rui grows very close and attached to Tsukasa very quickly, but Tsukasa only gets worse and worse.

   Be warned this is a middle school Rui Kamishiro x high school Tsukasa Tenma age gap au
