In a thread titled "Which endings are cannon from the first game?", the developers have explained the relationship between Seasons 1 and 2.

I think it's a good style to deliberately avoid a clear conclusion and give players some room for thought.

Hmm, that just seems to be sacrificing a sense of conclusion for the sake of making an ongoing story.

Hi there! This is the Five Hearts Under One Roof Season 2 team

Thank you for sharing your question about how the sequel connects to the first game. We understand why this is important, especially if you formed a happy ending with a specific character in Season 1 and want to know whether those choices are respected. Your curiosity about how the story continues shows how much you care about the world and its characters, and we truly appreciate that.

Season 2 is designed so that users can enjoy the story even without having a confirmed partner from the first game, but we hear your feedback about wanting the original endings to feel meaningful. We will proceed your thoughts to the related team so they can review this perspective as we continue to refine the experience.

We hope your time with the sequel will feel rewarding and immersive in its own way (•ᵕᴗᵕ•)

I think it's ok to have the first game treated as ending in a neutral way to facilitate a new season. I'd just like that to be communicated. Like, I'd see the second season as like an alternate universe story.

Although my pet theory is the second season takes place after the Seung Yi master thief ending from the first game.

Anyways, thanks for commenting, devs. I bought the first game on GOG and greatly enjoyed it.

If i was rich i would marry mai sook put a big rock in her finger, sadly im a loser but still happy i can cope with these games

You need also to be tall, Mal-Sook said herself you have to be al least 175 cm because she is 176.6 cm herself.

this game is superior to the first in every way

A couple of the characters carry over from 1 to 2 but they all start again from no relationship points with the MC or as if they have no previous with them as if they only know them as casual friends , which is a real shame . And a couple i really like have completely disappeared

Yeah, this is what I figured. The events of the first game, or something like it, happened but with an ending where the MC didn't end up with anyone.
