First time reading this my first thought was they both are so pure. I can see the uke is improving his courage a little and he want's to cherish the seme although his feelings aren't well received he was still trying. The seme may not understand the uke just yet but it's understandable they barely talk much about themselves and just went dating immidiently. The seme still treasure the uke which is very nice. He too has trouble expressing his feelings which is rather complicated. Luckly it's not too dramatized I would have drop it if it is there are conflicts still but I feel alright about it and it strikes me as interesting.

Could be the shield since it has purification buffs.
