This is so long... thanx if you read it at least

I want to get the name of a manga I've been thinking of recently. I read this manga quite a long time ago but I remember really liking it and being so hyped over it. I don't really have a vivid memory of it, but I'll try to thinking of things I do remember from it. It's kinda like a survival game, but it's in the after life. It has angels or demons that created a game for humans who die, and I think it's centered around a girl with glasses(maybe not). Honestly my memory of it is extremely vague, however I remember there being a scene where a timid girl with glasses finds out she killed her husband and she didn't even know it was him. The husband and her are very close to each other and they even opened a bakery with each other (they were highschool sweethearts), but they had debt from the money they borrowed, so the husband tried to do something about this debt involving him cross dressing, then he's suddenly on the run from some bad guys, then he falls out a window, and that's why how he ends up in the game, but unfortunately he melts to death during the game, and when the angel/demon who put them in the game tells her the truth she wants to die as well (she says her real name). Oh! And i just remembered something the reason why she doesn't recognise him as her husband is because when they're put in the game they get different names, and become different people to hide their identities or else they die. What they don't know is that they're all connected to each other. And the mc (who's a boy in the real world) has a little sister in the hospital, who's also involved in the game, but they don't know it because they have to hide their identities and they look like different people. Then at the end of one of the volumes they are lead to believe they can go back to the real world but theyre actually involved in a much bigger game, that has many rounds in it. And the reason the mc is competing in the game is because he wants to win the cash prize to afford to pay for a surgery for his little sister because she's sick and to be revived. Anyways that's all I remember, to the person or people who read this I really appreciate you, because I'm honestly so desperate, I cant get the thought of it out of my mind. I really appreciate
you for even bothering to read this, and if you have the answer then just know I will be forever grateful to you. It will even help if you have a clue that will help me find it. (=・ω・=)
