Sorry Guild Clerk you're very cute, hot and nice but our boy already has his wholesome and best girl wife waiting for him at home.
Emily being so happy about her own house to the point she's restless is the most wholesome thing ever.
Also about this dungeon, yeah DQ dungeon right there with the whole grinding for stat seeds. Don't surprise me because Dragon Quest is a big deal in Japan and with a good reason because DQ is the father of home console JRPGs and DQ3 became the role model for so many JRPG franchises thanks to introducing multiple classes. DQ on top of being the father of JRPG games is also the father of Isekais because so many stories take direct inspiration from DQ3.
But I think Ryouta was very dumb this time, dude before you go around risking your life try to better your gears, going alone solo into unknown dungeons with a bamboo spear is asking to be killed and leave behind your cute wife.
