I'm guessing Shouta was 10-12 and then timeskip ? T_T because in Bitter Like Light they're in university and they drink so I'm guessing they're at least 21... And since Shima senpai was with them in high school, they're either first years or second years so like 15-16 and timeskip to 21 which means they're like 6 or more years older WHICH WORKS BECAUSE Shouta would be a teen then... OMG IGNORE MY THOUGHT PROCESS THIS IS SO MESSY

Your thought process made sense, but I think that the boys would be about 25-28 after the timeskip because they were around 15-18 (second and third years) and Shouta looked around 7 or 8 before the timeskip, rather than 10-12. Therefore making the timeskip 10 or 11 years going by the fact that Shouta would be around 17 or 18 after. I don't know if this makes sense or if it seems right... I just thought it would be fun to think about. .+:。 ヾ(◎´∀`◎)ノ 。:+.
Teenager Shoutaaaaa hwaaa it shows how awet (what the heck is awet in english urgg) the relationship between the 2 pairs (it must be like 5-7 years later rite) i didnt expect senpai to be the uke tho it's quite refreshing ngahahaha
