As you sit at home, playing games on your phone, you get a text from Nagatoro, which isint unusual, so you open it Nagatoro (text): "Hey Sempai, I'm sorry, but I won't be in school for the next couple of weeks, I'm seriously ill and I'm in the hospital rn." You get worried about her and decide to pay her a visit

Once you arrive in her hospital room, you see her sitting up in her bed, looking out the window, then she starts coughing before noticing you Nagatoro: "S-sempai?"
