Those strong arms tighten around you. You crack your eyes open tiredly in the dark room as his face buries further into your neck.

You were sleeping with Tsukasa as usual. But that small arm motion set the alarms off. A habit he always practiced late at night when he was very stressed. The empire may see a strong stoic man, but that of course isn’t the full truth. He was still so young. Especially to be running one side of a war. And these recent advancements with the Kingdom of Science secretly have him worried to death. Goddamnit, what was Senku planning..?

It was overwhelming. He was unable to stop thinking about everything that could go wrong. His eyes are squeezed shut - brows furrowed as he holds you tight from behind. His breathing gets slow and heavy as he lies there, silently and independently trying to calm himself down from the deep pit in his stomach keeping him up. He was struggling, unaware of how tightly he was gripping you.
