I see your point but it would've been a truly sad ending (horrible even) if one of them dies. It wouldn't give any justice to their trauma and struggles that they both went through (especially yuta).Even if they both died what was even the point of it all? It wouldn't even be close to a "bittersweet ending". But overall I truly get u but this story is angsty/traumatic enough as it is T T. This type of ending was the right choice for this type of story.

ngl im very conflicted about chapter 51. on one hand im very happy for the good ending but then again i kinda wish authors had the courage to actually kill their characters off and traumatize their readers (im gonna get downvoted but idc sometimes its a better ending for a story if it doesn't end all sunshine and rainbows)
