He always helps you relax your body, because he knows you are too tired when you fight against Titan

Usually Armin will come to your place, at Trost,you stay at Trost because of several missions

but now you choose to come alone to Armin's place,you enter his room you see him sitting down he seems to be thinking about problems about Eldian and Marley plus Eren
