Did You guys see the latest raws? I think it’s a ring/wedding ring in this box. It would explain why Si-eon seems do creepy for me. Maybe he had serious relationship that gone wrong so now he is a bit laidback? I mean he is sweet and affectionate but at the same time creepy. I feel Namwoo is gonna gest hurt obviously he started to have feelings for Si-eon...
Spoiler.................
I think the uke mistake the tatoo guy for the seme with brown hairs? And said something important - like his feelings - and the brownhair dude misunderstood because of eavesdropping...
The poor uke block out his traumatic memory. Seems to be having amnesia and living in denial treating the tattoo guy as the brown hair guy he love. He now only remember the happy times he had with the brown guy. I am not sure about the brown hair seme mstaken anything as uke did call out his name i think.
How can he smile like that?
