First Love Again

Toru Nishina goes inside a coffee shop to meet a colleague,and he bumps into his old friend from high school,Kohei,who's now the shop's owner. Kohei doesn't seem to remember him at all,though,and only treats him like any old customer there. To be fair,they weren't "just friends," and their last goodbye was painful,to say the least. Will they be able to reclaim the past love they'd once lost...? (Source: Renta!) *Note: Includes the one-shot “Double Line”.*
