An intense flare in BL Lac S4 0954+65 was detected from February to March in 2015. Very-high-energy (VHE, (>150~mbox{GeV})) photons in the rising phase were detected by the MAGIC telescopes, while no such high energy photons were detected during other periods. The analytical particle transport model contains a variety of physical mechanisms in the jets of a blazar. Based on this model, we propose a scenario for the origin of the VHE photons. By increasing the temperature of the external Compton soft photons ranging from 800 to 45000 K, the multiwavelength spectral energy distribution containing MAGIC data points can be reproduced. The result suggests that the broad line region still may contribute to the inverse-Compton process when the emission zone is closer to the base of the jet, despite the fact that S4 0954+65 is a BL Lac type object.
