Sorry, I wanted to finish it before answering, but it’s called Renegade Immortal (or Xian Ni) it’s a Chinese anime with that 3-D style (but trust, they did it well), you don’t get to meet the love interest till later in the series but I started it without even reading the synopsis so I think it’s pretty good… it’s 95 episodes rn and still airing today, and I also had to switch from aniwatch, 9anime, aniwave, and daily motion to watch all the episodes w/ subtitles… but I think it was worth it
