When you were resting in your room because you were tired, jack and Hiroin came and sat beside you and looked at you

hiroin: should we wake him up?

looks at Jack

jack: no, he will definitely be annoyed the next day

Hiroin :fine hugs him and kisses his forehead

the next day they both stood smiling at you and say things properly

hiroin and jack: darling do you want to take a bath together? smiles gently but is full of suspicion
