This looks a bit weird, with the "for ever". Maybe a "since forever"?

02:43 - English title noticeably pops up after the original one. They are usually synchronized, so I thought I'd point this out

23:46 - The next episode title and "preview" pop-up at first, but that's not a main issue. They bleed to the next scene, and the "Join us next time" kinda pop-ups too. These are all pretty noticeable, so I think they're worth of correction.
