I am after the story where the sempai goes over seas for some time leaving his cute uke behind. The uke becomes a manly man in their time apart so says they just friends. Of course this is not how it ends up. The uke also makes really big bentos for his sempai?

thanks!

The fourth and fifth chapters of Katsubou no Manazashi seem to be what you are looking for.

yes! that is exactly the one! thankyou very much :-)
