I HAVE SEEMED TO HAVE SOLVED THIS VERY UNUSUAL ARG

the boxed images represent your first clues of the arg. if i am deciphering this correctly, "bango" is australian for "bang," so the son is watching research that has banging in it. but if you dig deeper, there are more secrets.

here i have boxed Kee-san, another XXX, SHI, KAT, NAG, A, S, A, K, and I. if i am reading this correctly, the son is watching research with banging in it. Kee-san which is obviously the most common name for dads, so the son's dad is having love (from the second XXX) with the son while he is watching research with banging in it. the SHI, which is an anagram of ISH, can be interpreted as FISH and stuff. the son could either have a FISH or stuff in his mouth, and/or the dad can have FISH or stuff in his mouth as well. KAT is a misspelling of CAT, but sound exactly the same, so the cat joins in with the dad having love with his son. NAG, A, S, A, K, and I come together to create NAGASAKI, so the dad has love with the son with the cat watching while the son is watching research with banging in it while the son either having stuff or fish in his mouth (or the dad), while a bomb is being set off at nagasaki, which means this incident occured during world war 2.
