I really felt sorry for Da Long, so I gave him a CP, so that at least he would have someone by his side when he was in the most pain. (It is originally fictional, so please don't get hung up on those details, thank you.)
Blood-stained ink is a sad name, but she never feels sad. Because she met him, at least she met him, fell in love with him, was happy and warm, so she never felt sad or regretted, even in the end...
Concept: Love is the warmest, responsibility is the most important
