Demon Slayer: Tanjiro, Please Always Look at Me, Okay?

[Contains a large number of cps, ginin, gitan and other cps. I will try my best to write down most cps without being OOC] Do you believe in love at first sight? Tsukishima Aoi didn't quite believe it at first, until he met that young man, Tanjiro. His smile was so gentle and his character was so tenacious. The smell of charcoal fire on his body made Tsukishima Yang feel obsessed, and every look in his eyes could make him tremble with excitement. He fell hopelessly in love with this young man. He confessed countless times, only to be rejected again and again, but it didn't matter. Tsukishima Aoi kept trying. But as he met more and more people, Tsukishima Ao was surprised to find that the time Tanjiro's eyes stayed on him gradually began to decrease. But he could do nothing but be an incompetent husband and continue to stay by Tanjiro's side aggrievedly. [There is a Shura field developed by Tanjiro]
