Leiyanna the fujoshi's manga / #Slice of life but really literalize it or smthn(1)

Its two teens left to their own devices as family is in honeymoon mode and they play house with an ACTUAL baby, getting the stereotypical "wow, you young parents" gag with the girl falling for him right away when they just met for a few days because of his actions. Its cliche and abrupt and a solid 3/10 since I don't know what to feel about this lol ╮(￣▽￣)╭ ----
