Shii finds and reads Tamaki’s “things not to do” notebook. So they had conversation and Tamaki finally told Shii everything (shii hugged and consoled him). And looks like after listening to him Shii fell into self-blame because he has been by tamaki’s side all the time but never found any clues. Then he offers tamaki to stay at his place overnight . After turning off the lights Shii suggested him to end one year dating contract ╥﹏╥
