I think he loved the step father the whole time, just like he did when he was a teenager. The difference between his bf and his step dad is that he never loved the step dad romantically: it's simply that he was willing to do whatever it took to stay together, so he accepted the sex. Therefore, I think he has left the tattoo because it was a gift from his step dad, and a memory, and something that still connects them.
Yup. The stepdad made that comment about (from memory), "one day you'll find someone who will entrust to you their whole weight", and basically Hanada trusts and adores Chouno, and Chouno adores him and treasures him right back. It's a reference to the bondage his dad does, about the sub entrusting their body to the dom, but also in a relationship. So it is implied that finally, finally Chouno has found someone who makes him happy and he has found his place
I am feeling confused at the end of chapter 2. Chouno decided to leave the tattoo and look at Hanada while Hanada was sleeping. Is it because he still love stepfather or he will face the past and he will live with his new lover forever? Someone please give me the explain. Thanks
