30kg-bun no Ai, Uketotte Kudasai!

Office worker Mamiya's hobby is walking around town sampling random food with her kindhearted fat friend, Teshihara. When Teshihara comes back from a year-long assignment, he looks like a totally different person! What's more, the first words out of his mouth are a confession of love.. This is all too much for Mamiya to take!
