It's a quickie 4-koma, 30 pages in total, you can probably bang it out in 15 minutes, with distractions. It starts from an accidental rejection in which Tsuyuki is caught off guard by Imao's confession. Imao takes it quite well, but since Tsuyuki had not planned on rejecting him, she's upset by the turn of events. She tries to figure out what to do, and due to being a bit dishonest about her feelings, is sucked into the usual 4-koma pattern of setting up and delivering a punchline in four panels. It's just unlucky that the ending is so unsatisfying. The jokes are worth afew quick smiles, but this could have continued for quite some time. I guess the author got bored and ended it on a poor note.
