Can someone tell me the name of this manhwa if you’ve read it? I genuinely don’t remember much . It was a BL manhwa, and I think the ML was a tiger or some kind of supernatural being who could take human form. I vaguely remember that, toward the end, he disappeared for around 1–2 years and then came back to the MC, and they eventually reunited. I think the MC waited for him during that time. It was probably set in a modern setting. I know this is extremely vague, but if this sounds familiar to anyone, please tell me the name!
