[Probably best to not leave Muramasa unsupervised, period. Although the fact the guy likes an audience is part of the problem...]

[Tonbokiri smiles warmly at the invitation.]

Yes, it would be an honour. [And then his eyes fall on the lines of poetry, and his eyebrows furrow with worry for an instant as the tips of his ears warm. He would genuinely like to spend time with Mikazuki again but-- maybe not over poetry, if it can be helped. His eyes find the teacup beside the papers, and he bows his head politely.]

If I may make a humble offer, it would be my pleasure to make macha for you.
If you would accept, please feel free to call upon this one any time.
