Recommendations Young husband and older wife with kid

[CheertheSecond]

Can you suggest a story with young husband (19 to early 20s) and much older wife (late 30s)?

I am looking for a story where the young man tries to fulfill his duty as a husband to his more mature wife and a father for his wife’s kid (from a previous marriage).

Prefer fluffy slice of life story.

I'll let you know if my husband dies or something, but my boyfriend is also over 30, so I'd have to find a new man to fulfill your request.
