have 你 ever watch an 日本动漫 that was really good but left 你 with a cliff hanger and 你 couldn't get the 图书 to see how it ends

Nope! nothing like that

Mahou sensou ( wells its my guilty pleasure but!!)! Someone got hurt, people were fighting, and there was a time jump all in the last episode! What happened next? Well I sure don't know since the 来源 material it was adapted from isn't available for me to read (well it might be online but I don't like 阅读 online) also low key rokka no yuusha since I thought all's well that ends well until they threw in that twist

unfortunately yes:

:/ decieving (crying internaly)

Gangsta. left me feeling this way. Luckily I found out that there is a 日本漫画 so in the future I do intend to read it.
